pixel-formats: add RGBA bits and type fields
These fields are necessary when looking for an EGLConfig matching a pixel format, but the configs do not expose a native visual id. Such happens on the EGL surfaceless platform where one does not actually care about the exact pixel format, one just cares it has the right number of bits for each channel and the right component type. FP16 formats are coming, so this paves way for them too, allowing them to be described. The FIXED/FLOAT terminology comes from EGL_EXT_pixel_format_float.
