For ShellExecute, if the specified file is found, we will try running it anyway, even if it doesn't
have a "program" extension.

Windows associations will take precedence over this.

So that the path returned by SHELL_FindExecutable would be fully qualified, otherwise CreateProcess
will do its own path resolution which is not what we want.

Fix a regression from ee0aad5c, which changes the virtual desktop display frequency to that of
the host display while adding modes of 60Hz. So when the host display is not 60Hz, we might get
ChangeDisplaySettings() failures when virtual desktop is on because the target mode is not found
because of the frequency difference.

And build it as x86-64 code on ARM64EC.
