[vm/kernel] Move functionality of Fuchsia's compiler.dart into pkg/vm

This includes:
* Selecting front-end target.
* Support for multi-root virtual file system.
* Not linking platform into resulting kernel file.
* Specifying input as URI (instead of file path) on command line.
* Automatically converting input script URI to package URI.
* Writing ninja dependencies file.
* Writing package-split kernel binaries.

After this change Fuchsia's compiler.dart will become a small wrapper
over pkg/vm, sharing most logic and even most command line options
with pkg/vm gen_kernel tool.

Also, this CL attempts to share some pieces of code between frontend
server and gen_kernel.

In addition, seperate bytecode generation for package-split binaries
is implemented (needed for https://dart-review.googlesource.com/c/sdk/+/85469).
