Previously, in the pr #150992 , export symbols only supported Linux. The special prefix and suffix rules for some symbols in macOS and Windows were not fully supported. This pull request attempts to clarify these rules and add corresponding support.

Currently, the undecorate_c_symbol() function has been added to handle macOS _ prefixes, Windows x86 calling convention modifiers (cdecl/stdcall/fastcall/vectorcall), and Arm64EC # prefixes.

Could someone pls give me permission to test whether the current modifications will work correctly on Windows and macOS?
Cause I don't have the corresponding devices.
