Map RGBX AHB to GL_RGBX8_ANGLE and fix the load function
AHARDWAREBUFFER_FORMAT_R8G8B8X8_UNORM was false mapped to GL_RGB8, which
will write back to the backing exteranl storage with 3 channel layout.
Angle actually has ANGLE_rgbx_internal_format to fix the mapping with
GL_RGBX8_ANGLE. However, the load function must align with GL_RGB8 if
the actual storage is 4 channel. This change also fixes that to use
LoadToNative3To4<GLubyte, 0xFF>.
