Function pointer variables should be colorized as functions when they're called.

Environment

• OS and Version: NixOS 24.11
• VS Code Version: 1.94.2
• C/C++ Extension Version: 1.22.2
• If using SSH remote, specify OS of remote machine: N/A

Bug Summary and Steps to Reproduce

Bug Summary:
Executing a function call from a function pointer has mostly the same relevance as any normal function call; as such it should be colorized in a similar way.

Minimal example:
Note how the syntactic token type is easily detected thanks to the parentheses (and is identified as "entity.name.function.c" for the bare function pointer and as "entity.name.function.member.c" for the function pointer struct member), but the semantic analyzer ignores this particular property

Steps to reproduce:

1. Define a function in a C or C++ file;
2. Place the functions' address in a function pointer variable;
3. Call the function from the variable.

Expected behavior:
In the above screenshot, the text f on line 11 and ptr on line 12 should be colorized as func on line 10 is (i.e. purple)
