[clang][riscv] add -menable-experimental-extensions

Browse Source 
When building with clang-13 the zba riscv extension triggers a build
failure unless this switch is set. Set it for now, though it appears to
not be necessary for clang 14 and above.

TODO: add a version check for clang for a series of switches set based
on version in engine.mk.
