The arch review of AIA spec is completed and we now have official
extension names for AIA: Smaia (M-mode AIA CSRs) and Ssaia (S-mode
AIA CSRs).
Refer, section 1.6 of the latest AIA v0.3.1 stable specification at
https://github.com/riscv/riscv-aia/releases/download/0.3.1-draft.32/riscv-interrupts-032.pdf)
Based on above, we update QEMU RISC-V to:
1) Have separate config options for Smaia and Ssaia extensions
which replace RISCV_FEATURE_AIA in CPU features
2) Not generate AIA INTC compatible string in virt machine

Changes since v2:
- Use env_archcpu() to get RISCVCPU * from CPURISCVState *
Changes since v1:
- Remove redundant "has_aia" parameter from riscv_cpu_pending_to_irq()
