Remove bookmark icon from top sites

[rebron]

Description

In preparation for giving users the ability to edit top sites, remove the bookmark icon to remove the icon clutter on top sites. This will also improve perf on the new tab page as we're not needing to check for bookmarked sites.

Steps to Reproduce

1. Go to brave://newtab
2. Ensure you have top sites.
3. Hover over a tile and notice bookmark icon.
4. Expected result is that bookmark icon is no longer there.

Actual result:

Expected result:

Future direction where we're only displaying one icon to edit or remove top sites.

Reproduces how often:

Removing QA Pass-Win64 as this will need to be rechecked on 1.9.x once uplift is approved and merged.
