fix(vstopi): fix vstopi result selection

* AIA Spec:
* Ties in nominal priority are broken as usual by the default priority
* order from Table 8, unless hvictl fields VTI = 1 and IID ≠ 9
* (last item in the candidate list above), in which case
* default priority order is determined solely by hvictl.DPR.

* If bit IPRIOM (IPRIO Mode) of hvictl is zero, IPRIO in vstopi is 1;
* else, if the priority number for the highest-priority candidate
* is within the range 1 to 255, IPRIO is that value; else, IPRIO
* is set to either 0 or 255 in the manner documented for stopi
* in Section 5.4.2.

fix(xtopi): fix m/stopi.IRPIO generation conditions

* If all bytes of the supervisor-level iprio array are read-only zeros,
* a simplified implementation of field IPRIO is allowed in which

* We are configurable and do not need to simplify the implementation.

fix(xiselect): set the minimum range for xiselect (#4594)

The miselect register implements at least enough bits to support all
implemented miselect values.
The siselect register will support the value range 0..0xFFF at a
minimum.
The vsiselect register will support the value range 0..0xFFF at a

fix(vstopi): remove SEI from Candidate 4 (#4533)

* if hvictl.VTI = 0:
* the highest-priority pending-and-enabled major interrupt indicated

* using the priority numbers assigned by hviprio1 and hviprio2.

* A hypervisor can choose to employ registers hviprio1 and hviprio2
* when emulating the (virtual) supervisor-level iprio array accessed
* indirectly through siselect and sireg (really vsiselect and vsireg)
* for a virtual hart. For interrupts not in the subset supported by
* hviprio1 and hviprio2, the priority number bytes in the emulated
* iprio array can be read-only zeros.

feat(CSR): allow most CSRR can be out-of-order issued and executed

* Add some comment on rdata in NewCSR.
* Allow CSRR not to block backward instruction.
* Here is **Inorder** CSRR list,
* fflags, fcsr,
* vxsat, vcsr, vstart,
* mstatus, sstatus, hstatus, vsstatus, mnstatus,
* dcsr.
* The reason for Inorder CSRR executed is that these CSR will be changed
by Use-Level instruction without any fence, and executing OoO would
get wrong result.
* Since there must be FENCE before reading any PMC CSRs, there is no
need to let reading PMC CSRs inorder.

fix(LSU): fix cbo instr exceptions and implementation (#4262)

1. typo.
2. `cbo` instr not produce misaligned exception.
3. `cbo zero` instr need flush `sbuffer`.
4. `cbo zero` sets mask correctly

fix(LSU): fix cbo instr exceptions and implementation (#4262)

1. typo.
2. `cbo` instr not produce misaligned exception.
3. `cbo zero` instr need flush `sbuffer`.
4. `cbo zero` sets mask correctly
5. Adding RAW checks to `cbo zero`.
6. Adding trigger(Debug Mode) checks to `cbo zero`.
7. Fixed several issues with the CBO instruction in NEMU.
----

In order not to create ambiguity with `io.mmioStout`, a new port of
`StoreQueue` is introduced for writeback `cbo zero` after flush sbuffer.
arbitration is performed in `MemBlock`, and currently, `cbo zero` has
higher priority by default.
`cbo zero` should not be writteback at the same time as `mmio`.

---
A check on `CacheLine` has been added to `RAWQueue` to ensure memory
consistency when executing `cbo zero`.
See this issues:https://github.com/OpenXiangShan/XiangShan/issues/4240
for specific issues.

---
The `cbo` instruction requires a trigger check.
