feat(diagnostics): Add all Targets view for diagnostics

[Josh-Matsuoka]

Fixes: #1796

Depends on #1730 cryostatio/cryostat#1051

Adds an all-targets view to Analyze/Thread-Dumps which allows the user to see a view of all of the thread dumps available in the archives.

To test:

• Check out this PR as well as feat(diagnostics): Add GraphQL support for thread dumps cryostat#1051
• Build everything and run smoketest with quarkus cryostat agent:
  bash smoketest.bash -O -t quarkus-cryostat-agent
• Test out the thread and heap dump base functionality
• Trigger a thread and heap dump from both the diagnostics card as well as the capture diagnostics page
• Check the target specific view for each (Analyze heap dumps and analyze thread dumps) and make sure the table renders and works as expected
• De-select the target to get the all-targets view
• Verify that the expected targets show up and the dumps for each are accessible

A few things I noticed:

1. when I create a thread dump, the notification text looks like: Thread Dump c5864e6e-23e2-4c6b-a4fe-c612f9f37f4b created for target: undefined. I think this is supposed to be the target alias or connection URL, not undefined.
2. when I go to the Analyze > Thread Dumps or Heap Dumps views and select a specific target, then delete a dump file, I get a success notification but the table does not seem to update
3. when I am on those same table views and clear the target selection so that I get the new All Targets table state, deletion fails with an HTTP 404 - or sometimes the Delete action item seems to be unclickable
