Fix proxygen-macros build issues in latest Rust

[bobomb]

This pull request updates the proxygen-macros crate to use the new std::arch::naked_asm! macro instead of the deprecated std::arch::asm! for naked functions. The change is applied across both the forward and pre_hook macro implementations, ensuring compatibility with the latest Rust conventions for inline assembly in naked functions. Additionally, the unnecessary options(noreturn) directive is removed from the assembly blocks.

Migration to naked_asm! macro:

• Replaced all uses of std::arch::asm! with std::arch::naked_asm! in the forward and pre_hook macro-generated functions to align with updated Rust requirements for naked functions. [1] [2] [3]

Assembly options cleanup:

• Removed the options(noreturn) directive from the inline assembly blocks, as it is not needed with naked_asm! and may be incompatible. [1] [2] [3]
