target/riscv: access configuration through cfg_ptr in DisasContext

The implementation in trans_{rvi,rvv,rvzfh}.c.inc accesses the shallow
copies (in DisasContext) of some of the elements available in the
RISCVCPUConfig structure.  This commit redirects accesses to use the
cfg_ptr copied into DisasContext and removes the shallow copies.
