aarch64: morello: add purecap ucontext support
Adjust ucontext layout for purecap ABI and add make/get/set/swapcontext implementations accordingly. Note: mcontext layout follows the linux sigcontext struct, in userspace *context functions rely on the c registers stored in the extension area and ignore the mcontext fields for x registers.
