Stacey Son ce6c541dcb bsd-user:Add AArch64 improvements and signal handling functions ...

Added get_ucontext_sigreturn function to check processor state ensuring current execution mode is EL0 and no flags
indicating interrupts or exceptions are set.
Updated AArch64 code to use CF directly without reading/writing the entire processor state, improving efficiency.
Changed FP data structures to use Int128 instead of __uint128_t, leveraging QEMU's generic mechanism for referencing this type.
