Add Ok Breakpoint Column

[hellovolcano]

Pull Request

🤨 Rationale

A client needs a breakpoint column for debugging workflows.
HLD + IxD

👩‍💻 Implementation

This component mimics the nimble menu button component, but in addition to the toggle events on click, also includes a context menu event to allow clients to set additional states.

Added:

• A fixed width table column
• toggle events to switch between enabling/adding a breakpoint and removing
• oncontextmenu events to track right-click/context menu actions
• BreakpointStateEnum to track states and visual styles for breakpoint states
• Blazor wrappers and examples

🧪 Testing

manual testing
added unit tests

@hellovolcano, Here's @msmithNI 's innovation day branch for an ok custom column type (aka a square breakpoint column 🟥): main...users/masmith/innovationDay-okTableColumn1

I haven't looked at either implementation but it could be useful to scan it for differences with your approach and ping him with any questions. (Note when we talked I misspoke about who had done this project, it is definitely Malcolm)

FYI @jattasNI -- I know we originally talked about adding a label provider for ok. I'm open to adding that later, but for this first review I just used stringsin the component itself.

Reviewed the ok-components changes with some rigor (not quite normal Nimble level but more than normal Ok level). Only just skimmed the Blazor changes.

Most of the feedback is nice-to-have for the Ok level with the exception of the tab focus getting stuck on the breakpoint.
