Move almost all [D2DPixelShaderSource] diagnostics to analyzers #757

Closed Sergio0694 closed 8 months ago

Description

This PR optimizes the diagnostics in the [D2DPixelShaderSource] generator. It moves these to analyzers:

Invalid return type
Missing D2D shader profile
Missing D2D compile options
Invalid HLSL source argument

It then further optimizes the diagnostics setup in the generator, by dropping the array builder entirely.
