monitor/hmp-cmds-target: add CPU_DUMP_VPU in hmp_info_registers()
Commit b84694defb added the CPU_DUMP_VPU to allow vector registers to be
logged by log_cpu_exec() in TCG. This flag was then used in commit b227f6a8a7 to print RISC-V vector registers using this flag. Note that
this change was done in riscv_cpu_dump_state(), the cpu_dump_state()
callback for RISC-V, the same callback used in hmp_info_registers().
Back then we forgot to change hmp_info_registers(), and 'info registers'
isn't showing RISC-V vector registers as a result. No other target is
impacted since only RISC-V is using CPU_DUMP_VPU.
There's no reason to not show VPU regs in info_registers(), so add
CPU_DUMP_VPU to hmp_info_registers(). This will print vector registers
for all RISC-V machines and, as said above, has no impact in other
archs.

target/arm: Bring VLSTM/VLLDM helper store/load closer to the ARM pseudocode
This patch brings the VLSTM and VLLDM helper functions closer to the ARM
pseudocode by adding MO_ALIGN to the MemOpIdx of the associated store
(`cpu_stl_mmu`) operations and load (`cpu_ldl_mmu`) operations.
Note that this is not a bug fix: an 8-byte alignment check already exists
and remains in place, enforcing stricter alignment than the 4 bytes
requirement in the individual loads and stores. This change merely makes the
helper implementations closer to the ARM pseudocode.
That said, as a side effect, the MMU index is now resolved once instead of
on every `cpu_*_data_ra` call, reducing redundant lookups

Expose generic_handle_interrupt() prototype and register it
