Fix up braille deprecations (#20458)
Closes #20431
Follow-up to #20390
### Summary of the issue:
In #20252, `source/braille.py` was split into the `source/braille/`
package. In #20390, the moved symbols were marked as deprecated.
Internal code that uses these symbols was not updated to use the new
paths, so logs are being flooded with deprecation warnings.
### Description of user facing changes:
None.
### Description of developer facing changes:
NVDA's logs should once again be useable.
### Description of development approach:
Marked the
`tests.unit.test_braille.test_publicSurface.TestBraillePublicSurface.test_deprecatedNamesReturnCorrectObject`
test as skipped.
For each symbol in:
* Searched NVDA's python code (`source/` and `tests/`) for that symbol.
* For each found instance:
* Updated it to use the new path; and
* Where the calling module did not already do so, imported the new
symbol's module.
* Commented out the redirect.
* Ran unit tests.
### Testing strategy:
Unit and system tests.
### Known issues with pull request:
None known.
