Subject: [PATCH] BaseTools: fix ucs-2 lookup on python 3.9
python3.9 changed/fixed codec.register behavior to always replace
hyphen with underscore for passed in codec names:
https://bugs.python.org/issue37751
So the custom Ucs2Search needs to be adapted to handle 'ucs_2' in
addition to existing 'ucs-2' for back compat.
This fixes test failures on python3.9, example:

FAIL: testUtf16InUniFile (CheckUnicodeSourceFiles.Tests)
