If there are shims packaged by convention in nupkg. Shim Repository will simply copy it to the right location.
The query interface ToolPackageInstance will be in charge of finding the shim folder and filter the right RID. Shim Repository will pick the right file after the folder is located since Shim Repository knows the shim name and it also book keep the files at uninstallation.
During development, due to the wrong adapter level. The mock duplicated too much logic. So, I corrected the abstraction level to lower (only create shim). And replaced the existing mock with a much smaller one without any atomic control and file move, copy logic. At the same time. The chmod, which is a IO action, causes problem during tests. So I added adapter layer to it and put it in Util.

* Update XML file to per TFM
* Add extra property to the fake project according to nuget
* Treat nuget fallback folder as offline cache for tool
* Require -g to install global tool
* Copy test asset during test project build
* Address code review on LockFileMatchChecker
* Get NETCorePlatformsImplicitPackageVersion from PackageDefinitions
* Edit and add missing loc
* Change LockFileMatchChecker to local function
* Adding comment
* Add to content instead of copy
