- enable minifier deadstripping for OpenGL shader format; bytecode is a 100% match with this change on multiple tested projects so it seems safe to enable
- deprecate FOpenGLFrontend; nothing in available code appears to inherit from it anymore so the API appears unnecessary. this makes the OpenGL shader format more similar to others (which do not expose compilation functions as API)

- mostly just replacing them AllowWindowsPlatformTypes.h / HideWindowsPlatformTypes.h
- some other files had both Pre/PostWindowsApi.h and Allow/HideWindowsPlatformTypes.h, so just removed
- some occasional include order changes.

- Remove the condition causing SCW to automatically exit after a single job if HLSLcc was used. This doesn't appear to be beneficial; HLSLcc uses a lot of memory but does not appear to leak it, so we're wasting time spinning up new processes unnecessarily here. This allows us to deprecated the associated field in the compiler output and function in IShaderFormat.
- Strip out compiler invocations stats; this was not accurate in some cases and it was decided after discussion that at this point the effort to fix the problems was not worth the utility we get from it.

The shader code output contains a little bit of plaintext such as I/O identifiers and the shader name, which was generated for the DXC backend in a way that prevents caching.
This unifies the shader name in the output code and improves the cache hit ratio for a Lyra cook from 0% to roughly 50% cache hits (for certain platforms).
