[PATCH 2/3] Revert "ShellPkg: Add Shell[Get|Set]RawCmdLine to ShellCommandLib"

[Ruiyu Ni <ruiyu.ni@intel.com>]

This reverts commit 0fcf8d4df85d861b6e721bd1d8abb449f05e15ed.
The above commit causes several regression of "echo" command:
1. Double quotes are not being stripped from the final text. UEFI Shell 2.2 section 3.4.5 chops out the quotes.
2. Output redirection is not working as expected. Text is being redirected, but the ‘> …’ text should not be.
3. Inconsistent special character handling.  For example, comments with # seem to be parsed out correctly, but handing of ^ is incorrect.
In summary, ‘echo “You are ^#1” > t.txt’ results in the below content in t.txt:
 “You are ^#1” > t.txt
