This allows us to better track all kinds of accesses to record
implementation classes in dart2wasm, which generates separate
record implementation class per record shape.
This change also allows us to remove mutable dispatch targets
which were used to implement dynamic accesses to record fields,
and make tracking of record field types more accurate
(record fields are now versioned per shape).
This is also a step towards inferring actual record types.

The VM can read native asset mappings from kernel.
Previous CLs already added support to embed native asset mappings for
one-shot compilation.
This CL adds support for adding native assets mappings to kernel files
created by the frontend_server with the incremental compiler.
The frontend_server accepts a `--native-assets=<uri>` at startup and
accepts a `native-assets <uri>` message on stdin as compilation
command.
The frontend_server caches the compiled native assets library.
When a `reset` command is sent to request a full dill from the
incremental compiler, the native assets mapping is taken from the
cache and added to the final dill file.
Split of DartSDK & flutter_tools prototype to land separately.

* Add an `targetOS` argument to `pkg/vm`'s `compileToKernel`,

* Add a new `--target-os` command line argument for all binaries
that use `compileToKernel` for clients to provide the target
operating system, if known.
* Add a new`"vm:platform:const"` annotation to certain field and
getters in the Platform class.
This annotation is used to annotate static getters and fields with
initializers where the getter body or field initializer must evaluate
to a constant value if the target operating system is known. This
annotation may be used outside the Platform class and in user code.
For example, this annotation can be used on a static `String` field
that is initialized with one value if `Platform.isWindows` is true
and to a different value if `Platform.isWindows` is false.
Note: If the const functions experimental flag is disabled, then
any annotated static methods can only contain a single expression
whose value is returned. If it is enabled, then the static method
is evaluated as if it is a const function with the special
handling of annotated static fields and getters above.
* Create a VM constant evaluator that evaluates uses of static getters
and fields marked with the above annotations when a target operating
system is provided.
* Use the new VM constant evaluator in the unreachable code elimination
transformer.

Adds support for `asset: 'asset-id'` in `FfiNative`s.
Symbols in assets are resolved by
1. the provided [asset] (the bulk of this CL),
2. the native resolver set with `Dart_SetFfiNativeResolver` in
`dart_api.h` (old behavior), and
3. the current process.
Symbols in assets are resolved by the Dart VM through the mapping
provided in the `vm:ffi:native_assets` library:
```
@pragma('vm:ffi:native-assets', {
"linux_x64": {
"<asset1>": [
"absolute",
"<absolute-path>"
],
"<asset2>": [
"relative",
"<relative-path>"
],
"<asset3>": [
"system",
"<system-path>"
],
"<asset4>": [
"process",
],
"<asset5>": [
"executable",
],
}
})
library;
```
There are 5 asset path types. Symbols resolved in these asset types are
resolved as follows.
A. Absolute paths are dlopened, after which the symbol is looked up.
B. Relative paths are resolved relative to `Platform.script.uri`, and
dlopened, after which the symbol is looked up.
C. System paths are treated as absolute paths. (But we might explicitly
try to use `PATH` in the future.)
D. Symbols looked up in Process assets are looked up in the current
process.
E. Symbols looked up in Executable assets are looked up in the current
executable.
The native assets mapping can be provided in three ways.
X. In the invocation to `gen_kernel` with the `--native-assets`
argument. This uses the gen_kernel entry point for compiling
kernel.
Y. By placing a `native_assets.yaml` next to the
`package_config.json` used by the isolate group. This works for
`dart <source file>` and `Isolate.spawnUri(<dart source file>)`.
This uses the kernel_service entry point for compiling kernel.
Z. By sending a String containing the native assets mapping when
invoking the kernel_service directly from within the VM. Currently,
only used for unit tests.

Weaken assertion in gen_snapshot requiring all libraries to have a loading unit as there can still be unreachable libraries:
- Google3 and Fuchsia will compile all the sources in a package to a single dill file, then present multiple input dill files to the AOT compilation. Since the set of libraries was derived from package membership instead of imports, many can be unreachable.
- When the root library's main comes from an export, the frontend's representation will incorrectly report the library containing main as the root library and the true root library may be unreachable from it.
Instead, assert only that surviving compiled code is assigned a loading unit.

If a library contained an entry point but was not reachable from the root library, it was not assigned to any loading unit and caused a null dereference in gen_snapshot. This is not possible with the standalone embedder, but is possible in Flutter because it passes multiple sources to frontend_server. E.g., `--source dart_plugin_registrant.dart`.

This change adds --source option to kernel compilers (front-end server
and gen_kernel). This option instructs compiler to include extra source
files into compilation even if they are not referenced from main
library.
TEST=Added test cases to pkg/frontend_server/test/frontend_server_test.dart
and pkg/vm/test/kernel_front_end_test.dart

The VM patch files contain many annotations that guide the TFA and the
VM compilation pipeline. Most of these are not relevant to dart2wasm,
and having the TFA look at these when running inside dart2wasm leads to
sub-optimal, and sometimes even unsound, results.
In order to enable sharing of patch files between the VM and dart2wasm,
the annotation parser is given a target flag to control which
annotations it should recognize and how to parse them. The annotation
parser thus becomes an abstraction layer between the concrete
annotations in the patch files and the parsed annotations that the TFA
sees.
Additionally, external members used by dart2wasm don't always have
external names. To support this, the signature shaker must skip all
external members, not just the ones with an external name. This makes no
difference for the VM, since all of its external members either have an
external name or are implemented in a patch file, making them no longer
external.

This CL changes the way dart: libraries are considered supported when
used in conditional imports or bool.fromEnvironment constant using
the "dart.library.*" values.
Library nodes now has an isUnsupported flag which is set according to
the "supported" property in the libraries specification. Furthermore
the Target now supplies a DartLibrarySupport interface that allows
targets to override whether dart: libraries are unsupported.
This allows the JIT/AOT to use the same platform file but still
consider dart:mirrors unsupported in AOT mode, and dart2js to consider
the internal library `dart:_dart2js_runtime_metrics` supported.
Furthermore, the internal handling is changed so that condition imports
and bool.fromEnvironments constants are computed through the same logic
for "dart.library.*" values, avoiding the need for passing these values
through the environment.
