Add (Android) UID to reported properties

[sheepmaster]

Problem Statement

I don't think the application UID is included in the properties reported by Sentry. This can be useful e.g. to figure out if an app is running in a work profile.

Solution Brainstorm

There are other APIs to get information about the current user profile (e.g. UserManager), but a lot of information can already be inferred just from the numeric UID.

@sheepmaster thanks for opening this up! You could utilize the beforeSend callback to modify any events before they're transmitted and modify the event (E.g. by calling event.setTag())
See our docs for more details: https://docs.sentry.io/platforms/android/configuration/filtering/#using-before-send

Closing this as this feature doesn't seem to be applicable to a majority of our users. And you can always use the manual APIs to enrich your events anyway.
