Increase NUM_ABI_IDS to support RISC-V VLS calling convention variants

The RISC-V fixed-length vector calling convention introduces multiple ABI
variants based on different ABI_VLEN values. Each variant requires a
separate ABI ID to maintain proper ABI compatibility tracking in GCC.
Increase NUM_ABI_IDS from 8 to 12 to accommodate these additional ABI
variants.

gcc/ChangeLog:

	* function-abi.h (NUM_ABI_IDS): Increase from 8 to 12.
