BaseTools/Tests: Verify unsupported UTF-8 data is rejected

Surrogate pair characters can be encoded in UTF-8 files, but they are
not valid UCS-2 characters.

For example, this python interpreter code:
>>> import codecs
>>> codecs.encode(u'\ud801', 'utf-8')
'\xed\xa0\x81'

But, the range of 0xd800 - 0xdfff should be rejected as unicode code
points because they are reserved for the surrogate pair usage in
UTF-16 files.

We test that this case is rejected for UTF-8 with and without the
UTF-8 BOM.
