Issue/13268 implement clear and apply actions

[malinajirka]

Partially fixes #13268

This PR adds the clear and apply action to the Activity Log Type Filter screen.

Note: Review by commits might be easier.
Note2: Checked items are not persisted when you go back to activity log and re-open the activity type filter. That's coming in the next PR.

Merge instructions:

To test:

1. My site -> Activity Log
2. Click on "Activity type" chip
3. Try to select multiple items
4. Click on the Clear action and notice all items get de-selected
5. Click on the Apply action and notice the screen gets dismissed

The rest of the functionality will be tested when the filter actually work - next week.

PR submission checklist:

@malinajirka - The clear functionality is not working for me, can you take a look - maybe I am doing something wrong?

[malinajirka]

@zwarm Could you please double check that you are on the correct apk/branch. I just retested it on 2 emulators and it worked as expected. If it still doesn't work for you, what device/android are you testing it on? Thanks!

I'm running: pr-13483-build-84851 on emulator Pixel 3a XL API 29. I re-downloaded the APK attached to this PR and tried again, no luck. @malinajirka

It works on emulator Nexus 5X API 24.
Doesn't work on emulator Pixel 4 XL API 30 either.

Created issue for the clear not working when tapping on checkboxes proper.
