target/arm: AArch32 VCVT fixed-point to float is always round-to-nearest
...
For AArch32, unlike the VCVT of integer to float, which honours the
rounding mode specified by the FPSCR, VCVT of fixed-point to float is
always round-to-nearest. (AArch64 fixed-point-to-float conversions
always honour the FPCR rounding mode.)
Implement this by providing _round_to_nearest versions of the
relevant helpers which set the rounding mode temporarily when making
the call to the underlying softfloat function.
We only need to change the VFP VCVT instructions, because the
standard- FPSCR value used by the Neon VCVT is always set to
round-to-nearest, so we don't need to do the extra work of saving
and restoring the rounding mode.

Convert the Neon float-integer VCVT insns to gvec, and use this

Note that unlike the VFP int<->fp16 VCVT insns we converted
earlier and which convert to/from a 32-bit integer, these
Neon insns convert to/from 16-bit integers. So we can use
the existing vfp conversion helpers for the f32<->u32/i32
case but need to provide our own for f16<->u16/i16.
