This almost completely splits the RunCommand API into sub-routines.
- the ProcessCommandLineToFinal API handles replacing the a found alias and any found environment variables. This will redirect "-?" to "help", if necessary. Upon return, the command line is complete and finalized. It may still have redirection in it, and those will get chopped off later (but no further modifications occur).
- the SetupAndRunCommandOrFile API handles updating and then later restoring StdIn, StdOut, and StdErr (and removing their information from the command line). It will call into RunCommandOrFile.
- the RunCommandOrFile API divides the logic to RunInternalCommand, RunScriptFile, or running an .EFI file directly.
- the RunInternalCommand API handles updating and then restoring Argc and Argv. It will run the internal command in between.
- the SetLastError API handles updating of the environment variable "lasterror"
- the DoHelpUpdateArgcArgv was changed to DoHelpUpdate and now works on the raw command line and not the argc/argv. This allows the processing to be moved earlier.
Note this change has the following positive side effects (this eliminates unnecessary step):
- Argc/Argv are only updated for internal commands (as they are library based)
- no Argv/Argc/StdIn/StdOut/StdErr processing is done for file system changes.
- The ProcessCommandLineToFinal API exists and it's critical to the ability to correctly pre-process split ("|") command lines ahead of time to verify their correctness.
