  [RISCV][GlobalISel] Fix fptosi/fptoui from half to i64 on RV32 (#222316)

The fcvt.l[u].h patterns are RV64-only, so RV32 had no rule for
`G_FPTOSI/G_FPTOUI` with `{s64, s16}.` The magnitude of a half is at
most `65504`, so with Zfh the i32 result of `fcvt.w[u].h` never
overflows and can simply be extended to i64.
