Module demangle Copy item path

Custom symbol demangling support.

By default, Tracy demangles symbols using the C++ ABI, which is not fully compatible with Rust symbol mangling.

With the demangle feature enabled, clients must register a custom demangling function. This can be done by calling the register_demangler! macro with either no arguments to use the default demangler, or with a path to a custom demangler function. See its documentation for how to use it.

Note that only one demangler can be registered at a time. Attempting to register multiple demanglers will result in a linking failure due to multiple definitions of the underlying extern "C" function.
