Also: address parts of #6897, primarily:
* remove the problematic aspect of bumping the last wid in our
TileData, when this could trigger a re-send of a previously
sent delta, causing tile corruption.
* instead append an empty wid entry.
* as an optimization - if the last entry is empty update
the wid - since re-sending an empty delta is of no
concern.
* simplify a number of code-paths that special-case zero length
deltas. All deltas now commence with 'D'.
* still track updates in the JS - by detecting empty deltas.
* shares more code and simplifies various paths.

Remove assert and allow delta messages to be handled even if
there is no keyframe. Although it might make sense to skip
delta messages if there is no keyframe, that causes some
content, at least in Impress documents, to not render.

It ensures that we pair un-subscription for a tile change with the
request - since we can have multiple tile requests in flight at a
given time.

We concatenate several deflated streams back to back, and need to
decompress and apply each one by one.

Squashed from feature/deltas-expanded.
TileCache changes:
+ add montonic sequence (wid) numbers to TileData
+ account for sizes of TileData with multiple blobs
+ simplify saving and notifying of tiles
Sends updates (via appendChanges) based on the sequence the
right mix of keyframes and/or deltas required as a single
message, and parse and apply those on the JS side.
We continue to use PNG for slide previews and dialogs,
but remove PngCache - used by document tiles only.
Annotates delta: properly as a binary package for the websocket.
Distinguishes between deltas and keyframes we get from
the Kit based on an initial un-compressed prefix
character which we then discard.
kit can be forced to render a keyframe by oldWid=0
Track invalidity on tiles themselves - to keep the keyframe around.
We need to be able to track that a tile is invalid, and so subscribe
to the updated version as/when it is ready - but we also want to
store the keyframe underneath any deltas.
force rendering of a keyframe for an empty slot in the TileCache.
force tile sequence to be zero for combinedtiles - so the client can
always request standalone tiles with explicit combinedtiles, or tile
requests.
move Blob to Common.hpp
use zero size for un-changed tiles.
remove obsolete render-id, and color deltas in debug mode.
cleanup unit tests for non-png tile results.

For each tile, the wire-id will grow incrementally for each key-frame
or delta appended; so we can tell which deltas to send.

Also, makes the logging of units much less error prone.
The overloaded streaming operators are temporary as
they are provided in C++20. The ones here (though
incomplete) are fashioned after the C++20 specs.

Stale tiles were still being counted, unhelpfully. Avoid doing lots
of ::now() calls, and yet detect this.

* Excised TileCacheDesc to improve performance and simplify code.
* clang-tidy suggestions and auto-rewrite fixes.
* Const-correctness.
* Inlined and improved a couple of trivial functions (that are called
often).
* Reduced some logs from INF to DBG as they are only meaningful to devs.

Saves lots of string construction and storage, simplifies lots of code.
Store the more exotic font-caching bits etc. in a separate store: we
should also pre-render these really and share them.

When we're doing the prerendering we also need to register
a tileBeingRendered object, so we know that the given tile
will arrive soon. In earlier version of the code, rendering
and sending of the tile was not separated in time, but now it is,
so we need create a tileBeingRendered object even if we don't
subscribe the client to it yet.
