[for-10.0,4/9] target/riscv: add shvstvala

Commit Message

shvstvala is defined in RVA22 as:

"vstval must be written in all cases described above for stval."

By "cases describe above" the doc refer to the description of sstvala:

"stval must be written with the faulting virtual address for load,
store, and instruction page-fault, access-fault, and misaligned
exceptions, and for breakpoint exceptions other than those caused by
execution of the EBREAK or C.EBREAK instructions. For
virtual-instruction and illegal-instruction exceptions, stval must be
written with the faulting instruction."

We already have sstvala, and our vstval follows the same rules as stval,
so we can claim to support shvstvala too.
