bug(android): Longpress keys don't apply special characters to keymanweb-osk.ttf

> The special characters on longpress keys on Android also don't render. (They show the text e.g. `*Alt*`). Is that Java or KMW code in #9187?

A separate issue needs to be tracked for this:

1. transforming the `*token*` patterns in the longpress captions in Java code (can't be done KMW side, because legit keyboards could use the same codepoints)
2. using the kmw font where the `*token*` captions are found (and only there)

Resolution for this depends on our decision on Android Longpress in the upcoming Keyman Planning Conference.

### Steps to Reproduce the Issue
On an Android emulator/device, install the 17.0 build of the /android/Tests/KeyboardHarness
1. Launch the KeyboardHarness app
2. Use the globe key to switch to the test9469 keyboard (exercises the special PUA characters in keyamnweb-osk.ttf)
3. On the default layer, longpress on the shift key
4. Verify tokens are shown instead of the special layers.
