shell32: Rely solely on SHELL_FindExecutable for ShellExecute.

This does two things:

1. ShellExecute no longer searches in the directory where the current
executable is in.
    2. We always CreateProcess with a fully qualified path, so we CreateProcess
won't do its own path
       resolution.

Serendipitously this also fixes some existing todos in tests.
