ben woodhouse 31208ca2a1 Add a new set of ASTC pixel formats for storing high precision normals in RG channels. The texture is encoded as LA for higher precision, swizzled to RG at runtime for shader compatibility with BC5. Requires RHI support. ...

Runtime pixel formats are named  PF_ASTC_<blocksize>_NORM_RG. Use texture format name ASTC_NormalRG_Precise for encoding.
