target/arm: Use FPST_A64_F16 in A64 decoder

In the A32 decoder, use FPST_A64_F16 rather than FPST_FPCR_F16.
By doing an automated conversion of the whole file we avoid possibly
using more than one fpst value in a set_rmode/op/restore_rmode
sequence.

Patch created with
  perl -p -i -e 's/FPST_FPCR_F16(?!_)/FPST_A64_F16/g' target/arm/tcg/translate-{a64,sve,sme}.c
