This reverts commit 0d88901a.

Reason for revert: Introduced a heap user after free in TabSearchButtonBrowserTest.TestBubbleVisible.

[my hunch is, it's just missing a call to tab_search_button()->bubble_for_testing()->Close()]

Original change's description:
> Tab Search: Update TabSearchButton tests
> 
> This CL creates a new file for TabSearchButton browser tests. These
> tests run for both the fixed and regular entrypoints.
> 
> Existing tests for the TabSearchButton have been moved from the tab
> strip into the TabSearchButton browser tests.
