gpu in-memory program cache implementation with a memory limit + lru eviction.

Wiring: 
- Added bindings for glProgramBinary, glGetProgramBinary, glProgramParameteri 
- Plumbed the shader cache from gl_channel_manager to program_manager 
- Program cache creation after first context is created 

Refactoring: 
- moved DoCompile to ProgramManager 

New: 
- added functionality to ShaderInfo to store if we have a possible pending cache compile 
- exposed attrib_map and uniform_map in ShaderInfo for the cache 
- program_cache base class with in-memory status storage 
- Simple memory_program_cache implementation, stores programs with lru eviction 
- Added caching logic to DoCompileShader and Link in ProgramMAnager 
- MemoryProgramCache, the in-memory cache implementation 
- ProgramCacheLruHelper, an O(1) lru implementation 

Misc: 
- A couple style fixes in modified files
