So far we were using raw uint32_t for handling masks. But this has the
issue that it only allows to handle up to 32 elements; if we need to
handle more elements, the we need to upgrade to uint64_t.
And this happened inadvertently with commit 370f02bf02 ("gallium: Bump
PIPE_MAX_SHADER_IMAGES to 64"), where the number of elements to handled
were increased from 32 to 64, but we didn't upgrade the mask type.
To fix this, and avoid this happening again in the future, let's use
BITSET, which is designed to handle bitmasks, and can able to handle as
many elements as desired.
