TPv2 context menu items that aren't multi-row should be disabled when multiple rows are selected.

[ocket8888]

This Bug Report affects these Traffic Control components:

• Traffic Portal (experimental v2)

Current behavior:

Non-multi-row context menu items on tables in TPv2 are not disabled when multiple rows are selected. Instead, they act on the actual row the user opens the context menu on instead of the entire selection.

Expected behavior:

Having context menu items within the same menu acting on different data sets depending on which one you choose is confusing. The intent was to allow users to easily perform single-row actions even if they have previously selected data, without any extra steps, but it would be more user-friendly to instead consistently represent the data set being acted upon by only allowing multi-row actions when multiple rows are selected.

I labeled this as a bug not because it is a bug, necessarily, but because people who experience it may believe it to be a bug rather than a misguided feature, so to promote visibility in case anyone opens a bug for that I'm labeling this how they would.

Steps to reproduce:

Use TPv2
