refactor: Remove redundant void argument from functions

[bobtista]

Summary

• Remove redundant void parameter from function declarations and definitions, e.g. f(void) → f()
• Applied using clang-tidy modernize-redundant-void-arg check across the full codebase (excluding Tools)

[greptile-apps]

Too many files changed for review. (2066 files found, 500 file limit)

[Stubbjax]

It would be great if f( void ) became f() instead of f( ).

There are also many places that are not covered as expected, such as GameWindow.h. Searching using regex (\b *)\(+ *void *\)+\B yields a further 1,091 results (excluding Tools).

added new commits for each, using regex to apply them

This is very welcome. This void is so annoying. Too big to inspect. Will cause conflicts on existing pulls.
