Pass integer texture format bit count to shaders on D3D11

This will be needed in the future when integer texture wrap mode support
will be added by sampling integer textures through FLOAT/UNORM/SNORM
SRVs.

The bit count needs to be passed for 8-, 10- and 16-bit textures. 32-bit
integer textures are the ones left over. Only passing the bit counts for
the absolute minimum number of formats avoids unnecessary driver constant
buffer updates.
