[RenderEngine] Organize RenderEngine directory.
This patch:
1. adds proper namespace renderengine to all RenderEngine code,
and namespace gl to all GLES related code
2. creates gl/ directory for GLES backend code
3. Reorder include header files, remove unused header files.
BUG: 112585051
Test: Build, flash, run display validation
