Import URIs are normalized by the CFE and should be globally unique in
the program. They serve as a good identifier to name a library in the
new "ddc" module format.

These new modules are only used when compiling with the `--canary`,
`--modules=ddc` and no other module formats.
This new flavor of the module system treats the output .js files as
a bundle of one or more Dart libraries.
In this change the Dart SDK module is still compiled with it's
libraries mixed together but exports them individually. Ideally this
is temporary and eventually they can be compiled in isolation as
well.
All other modules are compiled in isolation so class hierarchies many
may be broken until proper cross library linking is implemented in a
followup change.

When running in d8 the runtime flags need to be set by loading an
SDK with the same name passed for the application that gets used
when the application is started. If not the module system will
create an additional instance of the SDK module. This meant the
runtime flags were being set in one instance while the application
read them from another.
The same issue was present in the ddb script and this change fixes
it there as well.
Add the `--interop-null-assertions` option to the ddb script that uses
the runtime flag to enable null checks on non-static JavaScript
interop APIs.

- Introduces a new output subdirectory `gen/utils/ddc` where the
new build targets output files. This is intended to make the
migration to the new assets easier since landing this change
shouldn't immediately break any dependencies.
- Enables building the canary and stable assets at the same time.
- Changes more names in our workflow from "dartdevc" to "ddc".
- Updates the ddc-canary-linux-chrome and
ddc-canary-linux-chrome-unsound configurations to use the
new assets.
The new outputs appear in directories that are more consistently
named, (no more sound vs kernel confusion). They are named in
preparation for the eventual deletion of the unsound targets
without any lingering cruft to be cleaned up in the sound
directories.
The new structure is:
```
gen/utils/ddc/
|- canary
| |- pkg
| |- sdk
|- canary_unsound
| |- pkg
| |- sdk
|- stable
| |- pkg
| |- sdk
|- stable-unsound
|- pkg
|- sdk
```
The 'pkg' and 'sdk' directories all contain outputs with the same
files names, each compiled in the respective build modes
(sound/unsound and stable/canary).

This does not necessarily enable the native null assertions by default
everywhere but it is a step on the path to get there.
- The calls to the method that reads this value are only generated in
sound null safety so even if this is true the checks don't happen
in weak null safety. Added a warning when the option is enabled in
weak null safety.
- Many DDC integrations will set the flag manually during the bootstrap.
That setting still overrides the default value being changed here.

This change does a small fix to exclude line numbers from the golden
files produced by check_nnbd_sdk.dart. Doing so helps keep the golden
file more stable and less likely to require updates when developers make
unrelated changes to the core libraries.
There are very few failures that remain and now that the CFE is more
mature, we may be in a position to stop using the patch-sdk mechanism to
test the validity of the migrated sdk.

Simple calls to `List.generate` are expanded into a list allocation
and a loop. This generates better code for several reasons:
- There is no overhead for the function argument (closure allocation,
closure type, closure class)
- Global type inference is more precise since each List.generate list
is tracked separately, and the assignments in the loop give better
inference to the collection's element type.
To get precise element type inference, there are two new JSArray
constructors. Global type inference starts with the element type being
bottom for these elements, avoiding spurious nulls in the inferred
type.
