qemu: Document qemu_arch_available() method

Browse Source 
qemu_arch_available() is used to check if a broadly available
feature should be exposed to a particular set of target
architectures.

Since its argument is a mask of bits, rename it as @arch_bitmask.

We have less than 32 target architectures so far, so restrict it
to the uint32_t type.
