KVM: riscv: selftests: Split SBI FWFT into separate feature-specific sublists

Browse source

Divide the monolithic SBI FWFT (Firmware Features) register list into
separate sublists, each testing a specific FWFT feature independently
with proper dependency checking.

Previously, all FWFT features were tested together in a single sublist.
This caused issues because:
1. Not all FWFT features are available on all platforms
2. Some features depend on specific ISA extensions (e.g., pointer_masking
requires Smnpm)
3. Tests would fail if any single feature was unavailable

Add the feature-specific SBI FWFT sublists with the following
improvements:
- Add check_fwft_feature() helper to verify FWFT feature availability
  at runtime
- Update filter_reg() to handle per-feature FWFT register filtering
