Remove the option for Remote Access to play beeps (#18100)
Closes #18087
Summary of the issue:
Remote Access currently has the option to choose between sounds and
beeps for audio cues. This is extra code that we have to maintain, and
is not an option that is present elsewhere in NVDA.
Description of user facing changes
The option has been removed. Remote Access will only play audio cues.
Description of development approach
1. In `gui.settingsDialogs.RemoteSettingsPanel`, removed the checkbox
and references thereto that controlled this setting.
2. In `_remoteClient.cues`, removed the code that playes beep sequences
from `_playCue`, including `shouldPlaySounds`, as this is now always
`True`. Removed each `beeps` field from the various cues, and edited the
type definition of `Cue` to no longer include this field.
3. In `tones`, removed `beepSequence`, `beepSequenceAsync`, and
associated datatypes and imports.
4. Remove the `playSounds` option from the config spec, and the rename
from the `upgradeConfigFrom_16_to_17` function.
5. Edit the user guide to no longer refer to the "Play sounds instead of
beeps" option.
Testing strategy:
1. Tested opening, closing, and saving the Remote Access settings to
ensure that they still work as expected.
2. Started a Remote Access session, and sent the clipboard to make sure
various cues still work as expected.
3. Unit tests.
