riscv: Avoid using csrr instruction to test for vector registers

The csrr instruction isn't allowed in qemu user-mode, and raises an
illegal instruction error when it is encountered.

Therefore for now, we just hard-code that there is no support for vector
registers since the rest of the compiler doesn't support vector
registers for riscv.

Fixes #25312
