[accessibility] Interactive markers should be role="button"

[Malvoz]

Interactive markers (e.g. markers that bind to popups) are focusable and actionable elements, and should have appropriate semantics (i.e. role="button").

Related WCAG 2.1 Success Criterion: 4.1.2 Name, Role, Value (this issue is to address the Role part of the Success Criterion for interactive markers).

Hello, @mourner and @Malvoz!

I would love to help contribute to this project! I wanted to fork and clone the repo to get a feel for the code base before commenting on a specific issue, but I'm facing some difficulties getting the project up and running locally.
I am stuck at the step:

Install headless-gl dependencies https://github.com/stackgl/headless-gl#windows

In vsCode when I enter:
copy node_modules/headless-gl/deps/windows/dll/x64/*.dll c:\windows\system32

I get the error:
copy : Cannot find path 'C:\Users\dillo\gitRepos\Mapbox\mapbox-gl-js\node_modules\headless-gl\deps\windows\dll\x64' because it does not exist.

I believe I have all the packages installed correctly, any insight would be greatly appreciated!
