Pull Request Overview
This PR adds WebGPU backend support to the graphics system by implementing infrastructure for recording and submitting draw calls on render textures. The changes focus on introducing a new RHI abstraction layer, refactoring the existing OpenGL code, and implementing WebGPU command buffer patterns.
Key changes:
- Introduces TrRenderHardwareInterface (RHI) abstraction to replace the existing RenderAPI system, providing better support for multiple graphics backends including WebGPU
- Implements GPU command buffer infrastructure with WebGPU-style command encoders, render pass encoders, and command execution patterns
- Refactors rendering pipeline to support multiple execution passes (default frame, XR frame, offscreen pass) and improved context management

Missing equality comparison operator in the second strcmp call. Should be strcmp(disableStencilClearStr, "disable") == 0 to properly check if the string equals "disable".

Incorrect use of glGetIntegerv with texture target. Should use the appropriate binding constant like GL_TEXTURE_BINDING_2D instead of the texture target enum directly.

Typo in method name: 'shouleExecuteDrawOnCurrent' should be 'shouldExecuteDrawOnCurrent'.
