If the entrypoint is not a file URI, we'll crash as the strong components implementation is unable to find it. Fallback to the first library in the component

Adds support to the frontend server for producing javascript when
compiling with a target model of dartdevc. This uses the ProgramCompiler
and associated types from the dev_compiler package to output the kernel
AST into a "bundle" format.
dev_compiler:
* Exposes additional types needed for JavaScript compilation.
* Allows overriding CoreTypes instead of forcing it to be created from
Component. This is require to support compilation of the
partial Components created by the incremental compiler.
* provides extraIndexedLibraries in Target class so the CoreTypes produced by the incremental compiler have indexed them.
frontend_server:
* When the target model is dartdev, JavaScript is output instead of
kernel. For each Component we compile, we first compute the strongly
connected components and produce a List of new Components to interop
with the dev compiler. The file uri is used as module name.

Trying it out in flutter (for flutter test runs):
Running "flutter test" in flutter/packages/flutter:
BEFORE ENABLING
===============
$ flutter test --local-engine=host_debug
[...]
03:38 +5149 ~27: All tests passed!
$ flutter test --local-engine=host_debug
[...]
03:11 +5149 ~27: All tests passed!

08:37 +5149 ~27: All tests passed!
$ flutter test --local-engine=host_debug --coverage
[...]
08:21 +5149 ~27: All tests passed!
WITH THIS ENABLED
=================

08:34 +5149 ~27: All tests passed!
So, without coverage more than twice as fast!
With coverage ~no change (which makes sense considering it's the VM thats spending extra time collecting coverage, so the compilation is not the bottleneck).
Running "flutter test" in a new project created with "flutter create" (i.e. with a single test):
BEFORE ENABLING
===============
$ time flutter test --local-engine=host_debug
00:05 +1: All tests passed!
real 0m6.360s
user 0m8.783s

So maybe ~10% improvement on non-first runs (where it reuses the serialization from the dill it initialized from).
~no change on a clean run.

To support JavaScript compilation, the frontend_server will require a dependency on the dev_compiler. To avoid conflating this with the vm specific functionality, the frontend server will be split from its current location.
This change will require a small corresponding update in flutter/engine, documented in the patches directory
