riscv: Apply a static assert to riscv_isa_ext_id

Add a static assert to ensure a RISCV_ISA_EXT_* enum is never
created with a value >= RISCV_ISA_EXT_MAX. We can do this by
putting RISCV_ISA_EXT_ID_MAX to more work. Before it was
redundant with RISCV_ISA_EXT_MAX and hence only used to
document the limit. Now it grows with the enum and is used to
check the limit.
