Fix signature of dark-mode related uxtheme.dll functions

Browse source 
They were wrongly declared as taking (which is not very important) and
returning (which was very bad as it resulted to interpreting the return
values incorrectly in optimized builds) Win32 4-byte BOOL instead of the
C++ 1-byte bool that they actually use.

Closes #23169.

See #23186.
