5096 - Tabs Searchfield Close Button Resize/Fixes

[rob2d]

Explain the details for making this change. What existing problem does the pull request solve?

Search fields related to tabs had regression on close button; but also there was another issue where content of search field was not resizing. This is separate from the visual cutoff issue which pre-existed with the search field in tab headers (out of scope of PR).

Related github/jira issue (required):

Closes #5096 .

Steps necessary to review your pull request (required):

• pull 5096-tab-container-searchfield-close-button-fixes
• visit http://localhost:4000/components/tabs-module/example-category-searchfield.html and type some text in search field
• verify close button is vertically center-aligned
  
• visit http://localhost:4000/components/tabs-module/example-toolbar-with-spillover.html
• verify close button is vertically center-aligned
  

Included in this Pull Request:

• An e2e or functional test for the bug or feature.
• A note to the change log.

Implementation note: added resize trigger vs added logic to handler since another PR in review changes the existing callback to only check for breakpoint change event vs window resize as fix (to prevent any merge mistakes). So this change wouldn't be redundant once existing with that.

@rob2d - these seems fine as is , FYI i added a line of code so the theme switcher works in this example. When i did i saw that the text is a little offline in classic theme (sits a bit high)

If you want to add a fix - thats up to you. Willing to let it go in the interest of priorities/time...

@tmcconechy thanks for catching that/adding the theme fix. I tweaked the offset between classic/new also since that was very specific/quick to target on this branch.
