jason hoerner 046ace59ff ShaderCompiler: Preprocessor optimizations, first pass. Saves 16.7% overall on ConditionalPreprocessShader. ...

* Inline array memory allocation added to low level preprocessor for output and various temporary buffers to reduce dynamic memory allocation and reallocation overhead.  Saved 4.6%.
* FShaderPreprocessOutput::StripCode optimized to write to FString as TCHAR array, rather than using AppendChar (over 4x speedup).  Saved 2.9%
* Shader source file cache now also stores stripped and ANSI converted source, to avoid need to convert and strip the source, plus allocating a copy is avoided.  Saved 4.3%
* Uniform buffer structure declarations stored as ANSI converted source, avoiding convert and copy.  Saved 4.9%

Public

Shader Compiler: Made FShaderCompilerDefinitions private, to reduce code publicly visible in ShaderCore.h. For now, it's just marked deprecated for 5.4, but will be hidden more generally in 5.5.
