[3.12] gh-153030: Fix quadratic complexity in incremental parsing in HTMLParser (GH-153031) (#153041) 
gh-153030: Fix quadratic complexity in incremental parsing in HTMLParser (GH-153031)

When an unterminated construct (e.g. a tag or comment) spanned many
feed() calls, rescanning the growing buffer and concatenating new data
onto it were both quadratic.  New data is now accumulated in a list and
only joined and parsed once enough has piled up.
(cherry picked from commit bcf98ddbc4)
