* update branding

* remove stable properties from coreclr as it never stablises

* [release/3.0] Fix use of ilasm during test builds when using a 3.0 SDK (#27820)

* Add fix for restore of ilasm

The restore logic in buildtools tried to use a netcoreapp2.1 TFM for Linux-musl.
This ended up restoring Linux-x64 binaries which then broke the test build.
This change works around this by saving a copy of the depproj that BuildTools used into
the tree and restore it as a 3.0 app manually in init-tools on our side of the build.
