Revert "ShellPkg: Move FindFirstCharacter/GetNextParameter to ShellCommandLib"

This reverts commit c0bcd3433f33876c519bf5567e0ab69261b57fe9.
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
