[PATCH 5/5] target/riscv: Relax vector register check in RISCV gdbstub

[Jason Chien]

In current implementation, the gdbstub allows reading vector registers
only if V extension is supported. However, all vector extensions and
vector crypto extensions have the vector registers and they all depend
on Zve32x. The gdbstub should check for Zve32x instead.
