- 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)

da9b5b86f5 Do not include PreWindowsApi.h / PostWindowsApi.h directly in code. 
- 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.

5f85b46590 [shaders] remove unnecessary passing of hlslcc flags as an option to debug info output. this was just used to pass a switch on the SCW directcompile cmdline which SCW no longer does anything with. also cleaned up some additional unnecessary code related to these flags in backends that no longer use hlslcc at all.

efa00a9cb5 OpenGL: Avoid StorageImageWriteWithoutFormat SPIRV capability when compiling shaders for GL by adding a "-fvk_force_storage_image_format" flag that brings back old behavior (promote 3-component UAV to 4-component instead of using Unknown format). (author: Carl.Lloyd) 
Broken since 24910389.

49d7985a85 [shaders] Add "compile argument" functionality for generic parameters consumed by compile backends, along with helper to set both a compile arg AND define for cases which require both. The purpose of this is to move towards enforcing that preprocessor defines should _only_ be used during the preprocessing phase itself; the subset of defines that are currently used only as arguments to the compile backends (or used as both actual preprocessor defines and backend arguments) should use this mechanism instead. This allows us to explicitly identify and hash such parameters to be included in a stable key based primarily on a hash of preprocessed/deadstripped source; without it we would need to hash all defines which will defeat most of the deduplication benefit of doing this. A subsequent change will deprecate the GetDefinitions function on the shader compilation environment to enforce that defines cannot be read by anything outside of core shader system functionality.

5a8a3b3063 Unify shader debug name in shader code output for DXC backends to improve cache hits. 
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).
