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:
