Added another commit with support for the new //go:linknamestd directive that is new in Go 1.27

It got further. I think perhaps the new set of errors might have to do with the SSA changes for generics we were just discussing @jakebailey @aykevl

Added another commit that updates x/tools to a newer version that handles the new generics changes. The consequence of this is that the new minimum version of Go for TinyGo is 1.25, which is something that we also discussed in the monthly meeting.

For Windows, seems like you need the chkstk.S change for more platforms.

I think TestBuild/EmulatedCortexM3 is unavoidable, new json v2 is just larger.

I think I actually have all of the other failures figured out, but, not sure what to do with the fixes.

One or two of them I can send to dev first. E.g. when I added recover support, I totally forgot to also enable FailNow and SkipNow, and that's what some of the failure is.
