windows: Remove requirement to use cgo

[deadprogram]

This PR is an attempt to remove the requirement for CGo when using Windows.

Based entirely on the fine work of @jagobagascon including the hack to get around golang/go#55015

@jagobagascon I am able to run the scanner on Windows without installing any CGo build tool with this PR.

It runs the scanner exactly as expected, and does not display any errors. 😄

Seems to be working well enough for me.

I don't think the error is going to be fixed anytime soon. And let's be real, tinygo-org/bluetooth is probably the only use case for saltosystems/winrt-go so, would you like us to merge saltosystems/winrt-go#60?

If so, I think the PR should also include the "workaround" to avoid the deadlock error. I already made a change to include it: basically whenever a Delegate class is created a Goroutine with a timer is started, and it is automatically stopped when the object is released. That should completely avoid the deadlock error.

@jagobagascon tested saltosystems/winrt-go#60 and it worked perfectly. Once it is merged, I will replace the commit in this PR that updates the go.mod by pulling in the updated winrt-go and it should be good to go!

Merging since has been pretty well tested.
