  [RISCV] Update to Xqciint v0.4 (#130219)

The Xqci 0.7.0 spec just came out, with some updates to Xqciint,
bringing it to v0.4. The main update of any relevance is that
`qc.c.mienter` and `qc.c.mienter.nest` now update both the stack pointer
and the frame pointer (before, they only updated the stack pointer).
They both remain compatible with the frame pointer convention.

This change bumps the Xqciint version, and ensures that we don't emit
the unneeded frame pointer adjustment instruction after
`qc.c.mienter(.nest)`.
