BaseTools: Fix BrotliCompress tool issue

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2946

This is the regression issue in BaseTools BrotliCompress after Brotli
is changed to submodule. BrotliCompress should store the source size
and scratch buffer size into the header of the compressed binary data.
But now, BrotliCompress doesn't store them. So, BrotliDecompress
can't work.

To fix this issue, BrotliCompress tool main() function should be provided.
It needs to support the options of -e, -d, -o file, -g gap, -q level.
