arm64: fpsimd: Move sve_flush_live() inline

Currently sve_flush_live() is written in out-of-line assembly. It would
be nice if we could move it inline such that control flow can be written
more clearly in C, and to permit the removal of otherwise unused
assembly macros.

The 'flush_ffr' argument is redundant as sve_flush_live() is always
called from non-streaming mode, and all callers pass 'true'. Remove the
argument and make it a requirement that the function is called from
non-streaming mode.

The 'vq_minus_1' argument is unnecessary, as sve_flush_live() can read
the live VL directly using the RDVL instruction (wrapped by the
sve_get_vl() helper function).

Move the function to C, with the simplifications above.
