* Namespaces have been updated to reflect the move from //flutter/sky/shell to //flutter/shell.
* shell/BUILD.gn file has been split into smaller GN files for each subcomponent of the shell (common, GPU, diagnostic, testing).
* GN dependencies have been rewritten to stop exposing common shell dependencies as public. Duplicates have also been removed.
* GPU subcomponent has been updated make it more suitable for Vulkan integration.
* The GLFW backend has been resurrected.
The new boot sequence on Fuchsia now gives us the more accurate RGB_x888 pixel
format, which we should support. Also finish pushing pixels to the screen
before drawing new pixels.
Originally, this was a step that had to be carried out manually. Presumably because we did not want developers to download the Android SDK and NDK if they were not targetting Android. In practice, this is rarely the case. Even the buildbots unconditionally run the script (though they don’t need Android artifacts on the Mac since there is no Mac to Android builder).
This adds a flutter_services package responsible for exposing the Dart
interfaces exported by the engine in a uniform fashion, regardless of
how and where the generated code for the interfaces are organized.
We need to block in the surfaceChanged callback until we can swap the GL
surface with some content in order to avoid flashing transparent and then
black.

This patch makes three API changes:
* The dart:ui library now always communicates in physical pixels. The
framework is responsible for converting to whatever logical coordinate
system it wishes to use.
* The textBaselien property is now on TextStyle rather than ParagraphStyle,
which will let us choose which baseline to use on a per-span basis rather
than on a per-paragraph basis.
* This patch also removes the old MojoServices function endpoints.

This is partial revert of Iced1349e3ca750821d8882c551551f65bb569794.
Due to sorting of target family vectors, the font family order from XML
settings file is broken. Making unique operation stable doesn't fix the
issue completely since some font families are appended for the fallback
which also breaks the original order.
By this change, itemization becomes 3x slower than before if variation
selector is appended.
