Speed up package resotre of JIT Test build

We spend a fair amount of time (six wall clock minutes on my machine)
doing package restore for the JIT tests. This is because each project
has its own packages.config file, so during the build we call nuget
restore for each project.

There are only four unique packages.config files for all these tests, so
this change moves them to tests/src/JIT/config and updates the project
files to consume them from there.

This means during the build the `EnsureDependencies` target does not
need to invoke nuget restore as often and the build is much faster as a
result.
