Add 'Zfhmin' extension (#880)
Zfhmin is a subset of Zfh (half-precision IEEE 754 binary16 floating
point) extension, consisting only of data transfer and conversion
instructions.
This commit adds `EXT_ZFHMIN` to `isa_extension_t`, permits "zfhmin"
as a multi-letter extension and adjusts feature gate for
data transfer / conversion instructions.
* FLH / FSH
* FMV.X.H / FMV.H.X
* FCVT.S.H / FCVT.H.S
* FCVT.D.H / FCVT.H.D (if 'D' extension is also present)
* FCVT.Q.H / FCVT.H.Q (if 'Q' extension is also present)
