Delete :stream-chat-android-ui-utils module

[VelikovPetar]

🎯 Goal

Moves the extensions from the :stream-chat-android-ui-utils module to the :stream-chat-android-ui-common module, and removes the now empty module.

🛠 Implementation details

Moves all utility methods from the ui-utils module to the ui-common:

• io.getstream.chat.android.uiutils.model.MimeType -> io.getstream.chat.android.ui.common.model.MimeType
• Extensions in package: io.getstream.chat.android.uiutils.extension -> io.getstream.chat.android.ui.common.utils.extensions package
• io.getstream.chat.android.uiutils.util.EmojiUtil -> io.getstream.chat.android.ui.common.utils.EmojiUtil

Additionally, took the liberty to hide several methods from the public API:

1. Date.isInLastMinute is now private
2. String.containsLinks is now internal
3. String.addSchemeToUrlIfNeeded is now marked as @InternalStreamChatApi
4. Context.openSystemSettings is now marked as @InternalStreamChatApi
5. adjustColorBrightness is now marked as @InternalStreamChatApi
   All of there methods are extensions on non-Stream classes and pollute the public namespace. Since they are also internal logic, I don't see a reason to expose them publicly. (If you think we should keep them public, I will be happy the revert this change)

Added some missing tests.

Deletes the module and removes its usage.

🎨 UI Changes

NA

🧪 Testing

Not much to test, now customers don't need to add the ui-utils module, they can access the same methods from the UI SDKs.
