Partial revert of PR #11856 (PR #12695)
Fixes #12653
# Summary:
PR #11856 introduced speaking symbols when navigating by word.
The changes produced an unintended side effect of double processing symbols.
The text replacement for symbols gets spoken at symbol level all.
# Description of fix:
There isn't enough time before release to be confident in a fix for this behavior, instead the feature is reverted.
Reverting is in commit 619e5f7
Some changes have been kept:
- Symbol level enum: used in other aspects of the code and isn't a cause of this issue
- System test for notepad: Useful to confirm behavior for reading by word is not changed when this feature is re-introduced.
# Testing strategy:
Notepad system test
Generated and checked output of changes doc and userGuide
Ran NVDA with symbolLevelWordAll = True remaining in config (a problem here would only affect alpha users anyway).
