This property was only legitimately by the project which wants to
restore `crossgen`. Since that now comes from
Microsoft.NETCore.App (i.e. the shared framework) use
SharedFrameworkRid instead.
I also ensured that we passed UsePortableLinuxSharedFramework to
dotnet restore when restoring the tool projects, so we can use the
platform specific RID when non portable build.
Today we download crossgen for all supported runtime ids. This
introduces a dependency on having builds for all supported platforms
in order to build the CLI on a single platform. This is problematic
for the build from source effort because we only build artifacts for a
specific rid (the RID of the host/target).
Update the CrossGen.Dependencies project to restore for only the RID
we are building for.
* Add support to build with the linux portable
* Pass targets to run for the linux portable
* Address PR comments
* Update the bootstrapper version
* Address the PR comments for improving the help text
* Fixing permissions
Use the crossgen and jit that comes with Microsoft.NETCore.App so we don't have to keep a corresponding CoreCLR version around.
