Disable and tag tests failing in specific browsers

Pull Request

🤨 Rationale

One of the tasks in #1747 is to run nimble-components tests in WebKit and see if there are any new failures. There are several.

We also wanted to start tracking specific issues for each root cause rather than catch all issues like #1074 and #1075.

👩‍💻 Implementation

Marked each failing test with one of these specific issues:

• Disabled Firefox and Webkit tests due to webcompat dialog issue #1936
• Disabled rich text editor tests on WebKit #1938 TODO: ALSO FILE AZDO BUG
• Disabled interactive column sizing test on WebKit #1939
• Disabled TableColumnDateText tests on WebKit due to date formatting differences #1940
• Some table tests fail in WebKit and/or Safari due to focusedRecycleCallback #1942
• Drawer and dialog tests disabled on Firefox and Webkit due to unexpected DOM contents #1943

Also re-enabled a couple of table header tests in Firefox which are now passing.

🧪 Testing

Ran tests in Playwright webkit browser, Firefox, and Safari and and all the enabled tests now pass.
