Reverts #47678
Initiated by: jonahwilliams
This change reverts the following previous change:
Original Description:
Reland of #47432
Also includes:
Fixes the performance on iOS by removing blocking on compilation of shaders. From local testing this has identical before/after numbers. Additional, ensures that we don't unecessarily specialize vertex shaders and notes this restriction in the documentation.
Adds support for Specialization constants to Impeller for our usage in the engine. A motivating example has been added in the impeller markdown docs.
Fixes flutter/flutter#136210
Fixes flutter/flutter#119357
