target/riscv: Set [m|s]tval for both illegal and virtual instruction traps
Currently, the [m|s]tval CSRs are set with trapping instruction encoding
only for illegal instruction traps taken at the time of instruction
decoding.
In RISC-V world, a valid instructions might also trap as illegal or
virtual instruction based to trapping bits in various CSRs (such as
mstatus.TVM or hstatus.VTVM).
We improve setting of [m|s]tval CSRs for all types of illegal and
virtual instruction traps.
