BaseTools/Brotli: Fix compressed data loss issue
    
    REF: https://bugzilla.tianocore.org/show_bug.cgi?id=2946
    
    Currenly, when using the Brotli tool to compress data, the output
    compressed binary file does not record complete compressed data
    when size of input file is too large, which makes the data loss and
    will trigger decompress-check issue.
    
    The Brotli document mentioned:
    The brotli tool use BrotliEncoderCompressStream method to compresses
    input stream to output stream. Under some circumstances (e.g. lack of
    output stream capacity) the BrotliEncoderOperation would require
    several calls to BrotliEncoderCompressStream. The method must be
    called again until both input stream is depleted and encoder has no
    more output after the method is called.
    
    This patch fixes this issue based on the Brotli document.
