[CMD] Use GetFullPathName instead of copying buffers when resolving executable names

Browse source 
This properly strips spaces & dots at the end of the file.

Fixes the infinite loop with CreateProcess calling cmd over and over with e.g. 'cmd /c "some_script.bat   "'
Uncovered by recent ShellExecuteEx tests
Dedicated to Katayama for the trigger & Hermès for the tests
