Subject: [PATCH] [flutter_tools] remove SkSL bundling and dump skp on
 compilation. (#162849)

SkSL precompilation was only ever beneficial for iOS. For other
platforms, we recommended against it as Skia generated shaders per
target architecture which could be invalid on other devices. It is no
longer possible to use Skia on iOS.

Delete all Skia shader bundling logic.

Fixes https://github.com/flutter/flutter/issues/80091
