[Android] App crashes when Tab Groups or Conditional Tab Strip are enabled

[samartnik]

Description

App crashes when Tab Groups or Conditional Tab Strip are enabled from brave://flags. Tab Groups don't work with bottom toolbar, so in this case we just need to disable it. Conditional Tab Strip uses different bottom control and thus bottom toolbar should also be disabled.

Steps to reproduce

1. Enable Tab Groups or Conditional Tab Strip from brave://flags.
2. Exit app.
3. Start app, it will crash.

Actual result

App crashes.

Expected result

No crash and no bottom toolbar when Tab Groups or Conditional Tab Strip are enabled.
