Also updates StrongComponents to prefer the main component as the root if it is in a cycle. This makes bootstrapping more predictable.
This enables a clean integration of build_runner or ddr (internal) and the frontend_server by allowing it to work with any dev server.
All that is needed is a custom .packages file with `http` uris pointing at a dev server which does all code generation, etc.

Converts `package:` import uris into `/packages/` modules.
Also renames the output modules to append `.lib.js` instead of just `.js`. This allows us to distinguish between modules and applications based on extension.
Updates DDC source map code to be able to convert absolute file uris in sources so that they are relative to the source map.

This change fixes the issues causing build failures when using the
forked NNBD SDK sources and trying to build the dartdevc_kernel_sdk
target.
The end result is a dart_sdk.js file that is known to be incorrect
(missing uses of the legacy and nullable type wrapping) but serves
as a baseline for improvement. Some tests of the runtime directly
will correctly pass.
Following changes will turn on the type wrapping and we can start
diagnosing and fixing the issues that appear.

We are temporarily building a smaller SDK platform to make progress building
applications against the forked sdk_nnbd sources. This is because some of the
libraries have not yet been ported and they don't compose well.
I needed to thread the status of the non-nullable experiment through the front
end entry point and into the target options, and native types.
Also includes some standardization of the flag name in DDC.

* Disable all tests that run analyzer DDC.
* Detect the most likely case when invoked with an analyzer

I will follow up with deletions, and a rename of the test configurations/

The goal of this change is to make it possible to start iterating on nnbd tests
for DDC. This keeps the current philosophy of keeping NNBD and non-NNBD build
configurations separate, except that NNBD builds are allowed to consume library
sources from the non-nnbd sdk.
This change addresses the first set of errors that are encountered when trying
to build a fully NNBD configuration:
* CFE has issues with type promotion, for that reason we remove
`--enable-experiment=non-nullable` in vm build rules, and we use a smaller
training data when creating the dartdevc app-jit snapshot.
* We'd hit compile-time errors with nnbd libraries with inconsistent
patchfiles. To avoid that, the libarries.json points to the non-nnbd SDK
sources for most dart:* libraries.

This reverts commit 43cacafb51.
Patchset 1 is the original CL. Compare PS 1 to 4 to see additional fix.
It undoes an optimization that assumes private fields
are not overridden in the SDK. This patterns happens in dart:ui
and would be difficult to enforce now that flutter web also adds to
the SDK. As a result, all private SDK fields are virtualized, adding 0.7% to the size of
dart_sdk.js.

Note: Changes in this CL will require some google3 changes (mostly in code related to test entrypoints).
We encountered an issue whereby cross-module programs importing files
with the same name (but separate identities/locations) were being
overridden throughout all of DDK's module builders. For example, a
module importing "x.dart" and "y/x.dart" would export {x: x, x: x$} -
the latter renamed module shadowing the first. DDC handles this by
prepending a formatted module-root-relative identifier string, so
"y/x.dart" becomes something like y__x, and the export becomes {x: x,
y__x: y__x}. However, this results in some code bloat, especially as
paths become deeply nested. More importantly, the $-renaming scheme is
not consistent across modules. Were we to export x$ instead of x, how
would the importing library know whether x or x$ referred to "y/x.dart"?
To have the best of both worlds, we're introducing the concept of a
module alias that exists at the boundary of module imports and exports.
We use this module-root-relative alias to differentiate modules with the
same name but use the shorter $-renaming scheme throughout the generated
code. Relevant points:
1) jsLibraryAlias has been introduced alongside jsLibraryName.
jsLibraryName no longer must be unique - that property having been
transferred to the alias. DDK no longer just outputs pathSegments.last,
instead adopting DDC's scheme of "creating" a special alias from the
module root. jsLibraryName's temporary IDs are renamed using the
existing DDK scheme.
2) Libraries are now associated with NameSpecifiers. The name and asName
fields represent jsName and jsAlias, respectively, for exports
(vice-versa for imports).
3) The test frameworks have been taking advantage of DDK's previous
naming scheme (throwing way the module root, keeping just the name). A
common pattern is to expect DDK's output symbol to be "someexport", then
forcing DDC's output (normally "some__path__someexport") to resemble
that with the deprecated "library-root" flag set to the path of the
output JS file. We resolve this by updating the scaffolding code to look
for the module-root-relative (long) name, which requires a bunch of
path-to-identifier subsitution logic. The "absoluteRoot" bool in the
sourcemap test runner is a way to reenable this DDC-specific deprecated
behavior. The test runner now requires this alias in the html generator.

* `js` the const instance of a JSBuilder.
* `JS` the helper to inline javascript in the SDK patches

Ignore the lint in the js_ast directory to avoid additional diffs for the
eventual un-forking of the package.

Explicit casts make it easier to confidently navigate the code base and
apply refactorings which tighten types. This change exposes a number of
places where types can be tightened, but only the most trivial were
applied. For most places I added the explicit cast that would have
happened anyway and so behavior shouldn't be changing.
- Add the configuration which disallows implicit casts in the analyzer.
- Add explicit casts in almost all instances.
- Where the implicit cast was due to a local variable type on the left,
change it to a `var` so the type is not repeated.
- In a few places add argument types where they were already applied on
the parent type, and the subclass was unnecessarily loosening argument
types to dynamic.
- In a few places where a method was defined with an implicit dynamic
return but had an obvious and consistent return type, annotate the
method instead of casting after calls to that method.

Working towards turning on all lints from package:pedantic. This change includes
the lints that needed cleanup and don't change any behavior.
Applied cleanup:
* Don't explicitly initialize variables to null.
* DO use curly braces for all flow control structures.
* Use `.isEmpty` instead of `.length == 0`.
* Use `.isNotEmpty` instead of `.length > 0` or `! .isEmpty`.
* Use `=` to separate a named parameter from its default value.
The remaining lints from package:pedantic will require cleanup that is less
automatic and will be addressed in later changes.
