extmod/moddeflate: Add deflate module providing the DeflateIO class.

Browse Source 
This provides similar functionality to the former zlib.DecompIO and
especially CPython's gzip.GzipFile for both compression and decompression.

This class can be used directly, and also can be used from Python to
implement (via io.BytesIO) zlib.decompress and zlib.compress, as well as
gzip.GzipFile.

Enable/disable this on all ports/boards that zlib was previously configured
for.

This work was funded through GitHub Sponsors.
