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.

bsd-user:Add CPU initialization and management functions
Added function to initialize ARM CPU and check if it supports 64-bit mode. Implemented CPU loop function to handle exceptions and emulate execution of instructions. Added function to clone CPU state to create a new thread. Included AArch64 specific CPU functions for bsd-user to set and receive thread-local-storage value from the tpidr_el0 register. Introduced structure for storing CPU register states for BSD-USER.
