fix: fmv.h.x definedBy extension from F to [Zfh, Zfhmin, Zhinx] (#1058)

Fixes #1052 - fmv.h.x was incorrectly defined by extension F instead of
the proper half-precision floating-point extensions. Updated to match
the pattern used by fmv.x.h instruction.

Raedy for review sir @ThinkOpenly sir @dhower-qc
