lavc/g722dsp: optimise R-V V apply_qmf
This stores the constant coefficients deinterleaved, so that they can be
loaded directly with NF=0. Unfortunately, we cannot optimise loading the
input, due to insufficient memory alignment (not 32-bit).
Before:
g722_apply_qmf_c: 82.5
g722_apply_qmf_rvv_i32: 78.2
After:
g722_apply_qmf_c: 82.5
g722_apply_qmf_rvv_i32: 65.2
