Implement unorm_rgba8 and unorm_rg8 vertex formats.

Browse Source 
Backend support implemented in GL, Metal and D3D12.
Support for unorm values in the GL backend requires a
utility function to indicate if the format's components
are normalized.

Note that unorm_r8 is only supported on more recent MacOS SDKs (10.13),
so it's omitted for now.
