Sync eng/native with runtime

@hoyosjs, @mikem8361, can you please run other / official legs against the PR so we can validate there is no regression?

The only diff with dontet/runtime's eng/native (including dotnet/runtime#121071) is additional HAVE_PROCFS_MAPS_EXITCODE in tryrun.cmake (because the related code was moved from runtime to diagnostics, and this is needed by cross-compilation).

This probably breaks dbgshim packaging. I can run the official leg but see

diagnostics/src/dbgshim/pkg/Microsoft.Diagnostics.DbgShim.props

Lines 17 to 21 in d4961a0

	<ItemGroup>
	<None Include="$(NativeBinDir)$(LibPrefix)dbgshim$(LibSuffix)"
	PackagePath="runtimes/$(PackageRID)/native"
	Pack="true" />
	</ItemGroup>

We don't use targetRid since that's not correct on our packaging leg - we use a vertical for these packages since a fair number of our packages have RID assets from all different verticals.

Ah, good catch. In runtime, arcade, VMR etc. PackageRID/OutputRID were removed, we are using TargetRid. I've renamed them.

@am11 - do you see any use of HAVE_PROCFS_MAPS_EXITCODE? I couldn't see any referencing code.

[am11]

HAVE_PROCFS_MAPS is a feature check used in our code.

_EXITCODE is a convention used by CMake’s try-run infrastructure to store precomputed or cached results when cross-compiling. Since cross-compilation doesn’t have access to the actual target machine (for example, FreeBSD), the configuration introspection tests are executed on a representative target system beforehand, and the resulting exit codes are cached via _EXITCODE for reuse during the cross build.

[hoyosjs]

TargetRid sadly has different semantic meaning here. We pass it down.

/p:TargetRid="$__TargetRid" \

- in our packaging leg it's always win-x64.

@hoyosjs do you have a repro? I’m not sure what the intended forward path is; the goal of eng/native was to stay aligned with runtime, so new configs wouldn’t require duplicate engineering work.
