Fix issue with incremental build with globs.

Add a target that runs before CoreCompile that will record and store the
state of the Compile ItemGroup. This file is added to the
CustomAdditionalCompileInputs which is an input to CoreCompile. When this
file changes, CoreCompile will run again. This fixes the issue of deleting
a file or adding a file with an old timestamp to a glob (e.g. *.cs).

Fixes #1327
