02f6030dbd tool, tool/gocross: update gocross to support building natively on Windows and add a PowerShell Core wrapper script
gocross-wrapper.ps1 is a PowerShell core script that is essentially a
straight port of gocross-wrapper.sh. It requires PowerShell 7.4, which
is the latest LTS release of PSCore.

Why use PowerShell Core instead of Windows PowerShell? Essentially
because the former is much better to script with and is the edition
that is currently maintained.

Because we're using PowerShell Core, but many people will be running
scripts from a machine that only has Windows PowerShell, go.cmd has
been updated to prompt the user for PowerShell core installation if
necessary.

gocross-wrapper.sh has also been updated to utilize the PSCore script
when running under cygwin or msys.

gocross itself required a couple of updates:

We update gocross to output the PowerShell Core wrapper alongside the
bash wrapper, which will propagate the revised scripts to other repos
as necessary.

We also fix a couple of things in gocross that didn't work on Windows:
we change the toolchain resolution code to use os.UserHomeDir instead
of directly referencing the HOME environment variable, and we fix a
bug in the way arguments were being passed into exec.Command on
non-Unix systems.

b3e74367d8 tool: rename go.ps1 to go-win.ps1 for cmd.exe+Powershell compat
This tweaks the just-added ./tool/go.{cmd,ps1} port of ./tool/go for
Windows.

Otherwise in Windows Terminal in Powershell, running just ".\tool\go"
picks up go.ps1 before go.cmd, which means execution gets denied
without the cmd script's -ExecutionPolicy Bypass part letting it work.

This makes it work in both cmd.exe and in Powershell.

bb085cfa3e tool: add go toolchain wrapper for Windows
go.cmd lets you run just "./tool/go" on Windows the same as Linux/Darwin.

The batch script (go.md) then just invokes PowerShell which is more
powerful than batch.

I wanted this while debugging Windows CI performance by reproducing slow
tests on my local Windows laptop.
