Add zed-netcoredbg to csharp extension, add runnables

[Tiggilyboo]

This PR adds debugging support #12 as originally implemented by https://github.com/qwadrox/zed-netcoredbg I merged this code over for debug use. It uses netcoredbg: https://github.com/Samsung/netcoredbg

My PR adds runnables which detect test files, so test fixtures and individual tests can be run or debugged.

There is however one caveat, I can't seem to find a way to properly attach to the running test pid as we cannot inspect the process from within the extension. As seen in the screenshot below, the user can read and manually attach to the process id in the current implementation until a better solution is found. The only other way I can think of at the moment is to run the tests and output a temporary file which can be read by the extension, or somehow get the tcp connection working.

Open to other ideas, but at least this is one step forward to integrated test runnables from the csharp extension...

From my git commit log for more details:

• Use extension from https://github.com/qwadrox/zed-netcoredbg to have basic debug functionality with DAP and download netcoredbg for the running platform.
• Add runnables and tasks to debug from test files. Captures for nunit, xunit, vstest. Not strict, purely functional (does not pair keywords) to test framework.
• Currently unable to fully attach to runnable, but starts the vstest process so that it can be easily attached with PID listed in console

Just wanted to mention that netcoredbg isn't officially supported in MacOS for ARM architecture.

Yea, was made aware of this asking permission from the zed-netcoredbg repository: qwadrox/zed-netcoredbg#6 (comment)

Currently the extension pulls from the netcoredbg releases which builds this, but ideally we do not pull from there...

Is it a hard requirement that the debugging extension works with all zed targets? ie. Get this one through with a "MacOS aarch64 is not supported at the moment"?

As long as it falls back gracefully in MacOS ARM64 devices, it should be fine. Also having an explicit note on this somewhere in the extension README would be nice.

Not sure if it helps, but I've created a fork of the Samsung repo that keeps itself in sync with the upstream and automatically triggers builds of new releases. It builds for linux-x64, linux-arm64, macos-x64, macos-arm64 and win64.
