Adds a new jetpack compose and kotlin implementation of the sticker pack preview screen, which will soon replace `StickerPackPreviewActivity.java` and `StickerPackPreviewViewModel.java`.
- Uninstall selected packs in a single database transaction to avoid UI flickering.
- Add section header keys to prevent them from animating wildly while scrolling.
Our GlideImage implementation doesn't support animated images, because it loads them as bitmaps and therefore only displays the first image frame as a static image. This change works around that issue by having GlideImage wrap an ImageView to handle cases where we need to display animated images.
- Fix bottom action bar shadow clipping during visibility animations.
- Show snackbar after installing/uninstalling sticker packs.
- Navigate to sticker preview on row click.
- Add top app bar menu to enable multi-select mode.
- Start StickerManagementActivityV2 instead of the old StickerManagementActivity
Adds the ability to install sticker packs using `StickerManagementActivityV2`.
When the install button is clicked, it will morph into an indeterminate progress bar, which will then animate into a checkmark once the installation completes successfully. Then a couple seconds later, the sticker pack row will be removed from the available sticker packs list.
Showing exact progress for sticker pack downloads is more complicated than necessary. This PR updates `TransferProgressIndicator` to support displaying indeterminate progress.
#### Changeset
- Display indeterminate progress when installing a sticker pack.
- Remove cancel button from `AvailableStickerPackRow`.
- Decrease progress indicator size to match updated design.
Converts `StickerManagementRepository` to kotlin, so `getStickerPacks()` can return a `Flow` that emits updates after the database is changed.
This change simplifies the implementation of `StickerManagmentViewModelV2`, since `StickerManagementRepository.getStickerPacks()` will now automatically register and unregister the database observer.
Adds a skeleton implementation of `StickerManagementActivityV2`. This new activity is not currently connected to anything, but once complete it will replace `StickerManagementActivity`.
