* Read core platform kernel file during Dart initialization.
Currently service isolate is initialized from the source code parsed by VM.
This CL changes it so service isolate created during Dart initialization
is created from the kernel platform.dill file if it is present in the application
bundle. Then this platform kernel file is kept in dart_init module and reused
for application sciprt isolates.
* Reformat and merge
* Use accessor method
* Avoid passing running_from_kernel param. Add TODO for cleanup. Rename param.
- Assumes only the Dart VM is interested in idle notification.
- Gives the VM the time remaining in each frame.
- Gives the VM 100ms if there is no pending frame.
Issue flutter/flutter#9594
* Fix Flutter loading from dill files.
* Remove disable of causal async stacks.
* Include mirrors patch files as they are needed for release/profile gen_snapshot
* Free the bytes
* Add FTL_DCHECK
* This allows the tests to add their own FLX files but still use consistent fonts.
* The test fonts are only embedded on the desktop test shells. The option is not available on mobile platforms.
* Right now, all fonts will resolve to the test font. If we want tests to be able to use the fonts they embed in FLX files but use the test font for platform fallbacks, we will need to add font selector fallbacks. I can do this in an another patch. So far, there are no users of this functionality.
