fix(HTMLRewriter) buffer response before transform (#4418)

* html rewriter response buffering

* pipe the data when marked as used

* fix empty response

* add some fetch tests

* deinit parent stream

* fix decompression

* keep byte_reader alive

* update builds

* remove nonsense

* was not nonsense after all

* protect tmp ret value from GC, fix readable strong ref deinit/init

* fmt

* if we detach the stream we cannot update the fetch stream

* detach checking source

* more tests, progress with javascript and Direct sink

* drop support for pure readable stream for now

* more fixes
