An NVIDIA profile is applied to the current executable to disable
threaded OpenGL optimizations on Windows (see #71472). But because the
application is only added to the profile upon the profile creation,
newer executables won't be added to the profile (e.g. if the profile is
created on first launch of Godot_v4.1-stable_win64.exe, when users
update the editor and launch Godot_v4.2-stable_win64.exe, the profile
will never be applied to this new executable).
This patch fixes that scenario by splitting creating the profile (if it
doesn't exist) and adding the application (if it doesn't have a profile
applied) into two separate steps.
Applications that have been manually added to a different profile aren't
overriden to avoid confusing users who know what they're doing.
