There were two variants of string/wstring conversion utils, one using
codecvt_utf8 and the other using codecvt_utf8_utf16. We want the latter,
since we want to be using UTF-16, not UCS2.

This allows for targets to depend on the assets generated by the test_fixtures target.

Our tests depend on explicit latching to verify assertion are checked. If a test
does not respond for a long time, it has probably encoutered a deadlock. Instead
of waiting for the test runner to detect this, apply a very aggresive timeout on
a per test basis.

There are two issues in the test as written:
* There is a race on the first check to dtor_task_queue_id which might be
  encountered if the calling thread is de-scheduled and the unref queue manages
  to collect the object before the end of the scope.
* Two threads were owning a shared object but we relied on the object to be
  collected on the unref queue.

Added API guards to flags in PlatformPlugin that were introduced after Flutter's min SDK version. (#13965)

Fixes a bug where deleteBackward was checking for being at the start of
the text before checking for a non-empty selection, breaking deletion
when the entire text field was selected.

Also removes an (incorrect) post-deletion position update that was
redundant with code in insertText:replacementRange:, and thus having no
effect.
