We don't build a lot of tools with CGO, but we do build some, and it's
extremely valuable for production services in particular to have symbols
included - for perf and so on.
I tested various other builds that could be affected negatively, in
particular macOS/iOS, but those use split-dwarf already as part of their
build path, and Android which does not currently use gocross.
One binary which is normally 120mb only grew to 123mb, so the trade-off
is definitely worthwhile in context.

Tracking down the side effect can otherwise be a pain, for example on
Darwin an empty GOOS resulted in CGO being implicitly disabled. The user
intended for `export GOOS=` to act like unset, and while this is a
misunderstanding, the main toolchain would treat it this way.

Adds logic in gocross to detect environment variables and pass the right flags so that the backend can be built with the visionOS SDK.

The new 'toolchain' directive in go.mod can sometimes force
the use of an upstream toolchain against our wishes. Concurrently,
some of our dependencies have added the 'toolchain' directive, which
transitively adds it to our own go.mod. Force all uses of gocross to
ignore that directive and stick to our customized toolchain.

In this commit, we have updated the build process for our Windows DLLs
to link statically with libgcc, ensuring our Windows DLLs are self-contained.

So we can experiment with disabling static linking for tests in CI to
make GitHub Actions output less spammy.

We're going to need to build a DLL containing custom actions for the installer.
This patch adds the foundations of that capability to dist and gocross.

It's used to control various opt-in functionality for the macOS and iOS
apps, and was lost in the migration to gocross.

Xcode changed how/what data it exports to build steps at some point
recently, so our old way of figuring out the minimum support version
for clang stopped working.
