AppFwk: Move include of windows.h to top of file

The include was located in the middle of a file inside a namespace caf
block and lead to ambiguous symbols when compiling with unity build and
Qt6. It is also considered good practice to have includes at the top.

The pragma warning disable is also removed as the warning seems to be
gone (and none of the other windows.h includes have it).

Closes #11327
