Update TransferProgressIndicator to support indeterminate progress.

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.
