Remove deprecated functions which are older than 1 year

[andrews-moc]

⚠️ Bitrise is failing because Core SDK release with updated Authentication.java is required.

What was solved?
[Android] Developers want to remove deprecated functions which are older than 1 year

Release notes:
Remove deprecated functions and resources which are older than 1 year

Migration guide:

Before	After
Authentication.kt
authenticate(requestCallback: RequestCallback<Void>, jwtToken: String)	authenticate(jwtToken: String, externalAccessToken: String?, requestCallback: RequestCallback<Void>)
CustomCardAdapter.java
isInteractable(ChatMessage message, int viewType)	Nothing. The result of isInteractable() did not affect the behavior of the input field. The chat input field was always active anyway.
colors.xml
R.color.glia_transparent_black_buttons_bg	R.color.glia_call_control_buttons_color
R.color.glia_transparent_black_bg	R.color.glia_call_view_background_color

• Feature
• Ignore
• Release notes (Is it clear from the description here?)
• Migration guide (If changes are needed for integrator already using the SDK - what needs to be communicated? Add underneath please)

Additional info:

• Is the feature sufficiently tested? All tests fixed? Necessary unit, acceptance, snapshots added? Check that at least new public classes & methods are covered with unit tests
• Did you add logging beneficial for troubleshooting of customer issues?
• Did you add new logging? We would like the logging between platforms to be similar. Refer to Logging from Android SDKs → Things to consider for newly added logs in Confluence for more information.
