build: ship a Win11 build of Terminal that's <=half the size (#12560)

Four (4) squashed changes, with messages preserved. ## release: move symbol publication into its own phase Right now, symbol publication happens every time we produce a final bundle. In the future, we may be producing multiple bundles from the same pipeline run, and we need to make sure we only do *one* symbol publication to MSDL. When we do that, it will be advantageous for us to have just one phase that source-indexes and publishes all of the symbols. ## Remove Terminal's built-in copy of the VC Runtime This removes the trick we pulled in #5661 and saves us ~550kb per arch. Some of our dependencies still depend on the "app" versions of the runtime libraries, so we are going to continue shipping the forwarders in our package. Build rules have been updated to remove the non-Desktop VCLibs dependency to slim down our package graph. This is not a problem on Windows 11 -- it looks like it's shipped inbox. **BREAKING CHANGE**: When launched unpackaged, Terminal now requires the vcruntime redist to be installed. ## Prepare for toggling XAML between 2.7.0 and -prerelease on Win11 common.openconsole.props is a pretty good place to stash the XAML version since it is included in every project (including the WAP project (unlike the C++ build props!)). I've gone ahead and added a "double dependency" on multiple XAML versions. We'll toggle them with a build flag. ## Run the release pipeline twice, for Win10 and Win11, at the same time This required some changes in how we download artifacts to make sure that we could control which version of Windows we were processing in any individual step. We're also going to patch the package manifest on the Windows 11 version so the store targets it more specifically. On top of the prior three steps, this lets us ship a Windows 11 package that costs only ~15MB on disk. The Windows 10 version, for comparison, is about 40.

-    For our release builds, we're just going to integrate the UWPDesktop CRT into our package and delete the package dependencies.

-    and deployable everywhere. Since these libraries can be redistributed, it's easiest if we simply redistribute them.
-    See also the "VC LIBS HACK" section in WindowsTerminal.vcxproj.

+    depend on the desktop CRT. This lets us unify the Windows 10 and Windows 11 builds around a common CRT.

  <!-- This is magic that tells msbuild to link against the Desktop platform
       instead of the App platform. This you definitely want, because we're not
       building a true universal "app", we're building a desktop application
-       with xaml. APIs like CreatePseudoConsole won't always be linkable without Desktop platform,
-       but we now carry our own copy of them in the winconpty library which works everywhere.
-       For future reference, _VC_Target_Library_Platform can be configured to say which CRT to link against.
-       Now that this doesn't say anything, the implicit is 'Store' which links against the App CRT.
-       The alternative is 'Desktop' which links against the usual CRT redistributable.
+       with xaml.
       Linking against the App CRT will require the VCRT forwarders to be dropped next to the final binary for
       desktop situations, but it will let non-desktop situations work since there is no redist off desktop.
       The forwarders can be found at https://github.com/microsoft/vcrt-forwarders and are already included
       in our CascadiaPackage project.
