Add new "push_*()" functions to GDScript

[YeldhamDev]

• Added to GDScript the new log functions from Add new log functions for C#. #23345.
• Made some small changes to print_debugger(), mainly making it show the function name as well.

I really think these should be named something like debug_error() and debug_warn() (most print*() functions should be renamed to be honest), but I'm sticking with the original names from that PR for now.

How is this different from printerr, and could that functionality be added to printerr?

[neikeq]

printerr is equivalent of print that prints to stderr instead of stdout.

It's not the same as error macros like ERR_PRINT which does way more than printing to stderr (like coloring, function and line information, editor/debugger).

I like the feature, but I don't think log_* is a good name, as there's no relationship to a logging mechanism (does not write to a log file, etc.). I guess the intended meaning was something like register_error (in the debugger's error stack).

I'd suggest push_error and push_warning, as it basically just adds a new error/warning to the debugger's stack.

@akien-mga

does not write to a log file, etc.

Actually it does, it's just that it only writes that it was called from inside the cpp file, which basically makes it useless there:

**ERROR**: Example
   At: modules/gdscript/gdscript_functions.cpp:729:call() - Example

Also, I can change the function names, but then I will have to change them in the C# side as well.

Thanks!
