[RISCV] Add Qualcomm uC Xqcili (load large immediates) extension (#130012)

The Xqcili extension includes a two instructions that load large
immediates than is available with the base RISC-V ISA.

The current spec can be found at:
https://github.com/quic/riscv-unified-db/releases/tag/Xqci-0.7.0

This patch adds assembler only support.

[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)`.

[RISCV] QCI Interrupt Support (#129957)

This change adds support for `qci-nest` and `qci-nonest` interrupt
attribute values. Both of these are machine-mode interrupts, which use
instructions in Xqciint to push and pop A- and T-registers (and a few
others) from the stack.

In particular:
- `qci-nonest` uses `qc.c.mienter` to save registers at the start of the
function, and uses `qc.c.mileaveret` to restore those registers and
return from the interrupt.
- `qci-nest` uses `qc.c.mienter.nest` to save registers at the start of
the function, and uses `qc.c.mileaveret` to restore those registers and
return from the interrupt.
- `qc.c.mienter` and `qc.c.mienter.nest` both push registers ra, s0
(fp), t0-t6, and a0-a10 onto the stack (as well as some CSRs for the
interrupt context). The difference between these is that
`qc.c.mienter.nest` re-enables M-mode interrupts.
- `qc.c.mileaveret` will restore the registers that were saved by
