Chinmay Garde 16731be1a7 [Impeller] Allow for the specification of pipeline stage information at runtime. (flutter/engine#33882) ...

Towards implementing the FragmentProgram API in Impeller.

Specifies an Impeller specific format for data the renderer can use to create
pipelines with user supplied shader stages at runtime.

The data is in the form of a flatbuffer with a known schema.

This patch implements the wire format, creating and loading the program
payloads, and creating pipeline state objects using these payloads.

If the user supplied SPIRV intended for the older API, the loader will reject
this invalid payload. This is probably not going to be too much of an issue
because the FragmentProgram API will probably be modified to only allow buffers
loaded from asset managers. But still, in the meantime, I am using the old API
to pass these new buffers.
