Cole Robinson 5d8648345c 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)

    FileIn = UniFileClassObject.OpenUniFile(LongFilePath(File.Path))

    UniFileClassObject.VerifyUcs2Data(FileIn, FileName, Encoding)
  File "/builddir/build/BUILD/edk2-edk2-stable202002/BaseTools/Source/Python/AutoGen/UniClassObject.py", line 312, in VerifyUcs2Data
    Ucs2Info = codecs.lookup('ucs-2')
LookupError: unknown encoding: ucs-2
