fix(editor): single-letter tags in select/multi-select table cell (#14808)

### Summary of Changes
Resolves #14715 and #14280.

When a user types into a **Select/Multi-Select** table cell to
create/choose a tag, that character is stashed on the cell container
(setTagDraft) instead of going through valueSetFromString. Opening the
tag picker reads it via consumeTagDraftFromTableCellHost.

### Verification
- Added unit test to check that single-character input doesn't
immediately call valueSetFromString.
