  Improve language on evictable entries. (#3131)

* Improve language on blocking entries.

Remove "insertion has been acknowledged" phrase to avoid confusion
between Header Acknowledgement instructions implicitly acknowledging
encoder stream instructions and explicitly acknowledging header blocks.
Use Known Received Count instead.

Clarify that references on the encoder stream do not block an entry from
eviction.  Trivial as it is, I overlooked this at first, and added quite
some unnecessary complexity that was eventually removed at
https://quiche.googlesource.com/quiche/+/b09d44167c543b80b2c27408dd1f9df3b07c9741.
My motivation here is to help future implementers to avoid this pitfall.

Merge redundant Reference Tracking section into Blocked Dynamic Table
Insertions.

Change style of "Note" at end of section for consistency.  There were
already four sentences starting with "Note that" throughout the draft
before this PR (now there are six), but no other "Note:" markdown.

* Revert changing acknowledging insertion to comparing absolute index to Known Received Count.

* Remove unnecessary wordcrafting to blocked-insertion first paragraph.

* wordsmithing

* nit

* Minor rewording
