RISC-V: shunt isa_ext_arr to cpufeature.c
To facilitate using one struct to define extensions, rather than having
several, shunt isa_ext_arr to cpufeature.c, where it will be used for
probing extension presence also.
As that scope of the array as widened, prefix it with riscv & drop the
type from the variable name.
Since the new array is const, print_isa() needs a wee bit of cleanup to
avoid complaints about losing the const qualifier.
