This patch aims to help breaking down the long function present in
the ShellPkg and reduce complexity/nested code and conditions.

Return directly if ShellCommandLineParse() returned an error Status.
In such case, the "Package" that should be allocated by
ShellCommandLineParse() is already freed in:
ShellCommandLineParse()
\-ShellCommandLineParseEx()
\-InternalCommandLineParse()
so there is no need to free it with ShellCommandLineFreeVarList().

No functional change should be induced by this patch.

This patch aims to help breaking down the long function present in
the ShellPkg and reduce complexity/nested code and conditions.

Extract a MainCmdXXX() function for each shell command.
This command contains the possible operations the command aims
to operate. The ShellCommandRunXXX() function from which it
is extracted is only responsible of:
- initializing the shell/command environment
- parsing the command parameter and creating a Package
- freeing the Package

No functional change should be induced by this patch.

Extract a ProcessFileList() in:
- Touch.c
- Type.c
to lower the indentation level and simplify the logic.

No functional change should be induced by this patch.
