[Clang][RISCV] Guard vector float16 type correctly with semantic analysis
Before this commit, vector float 16 types (e.g. `vfloat16m1_t`) of RVV
is only defined when extension `zvfh` is defined. However this
generate inaccurate diagnostics like:
```
error: unknown type name 'vfloat16m1_t'
```
This commit improves the compiler by guarding type check correctly
under semantic analysis.
