Note that this must run before every invocation of CoreCompile to ensure that all compiler
runs see the generated assembly info. There is at least one scenario involving Xaml
where CoreCompile is invoked without other potential hooks such as Compile or CoreBuild,
etc., so we hook directly on to CoreCompile. Furthermore, we  must run *after*
PrepareForBuild to ensure that the intermediate directory has been created.

To allow version changes to be respected on incremental builds (e.g. through CLI parameters),
create a hash of all assembly attributes so that the cache file will change with the calculated
assembly attribute values and msbuild will then execute CoreGenerateAssembly to generate a new file.

GetAssemblyVersionParses the nuget package version set in $(Version) and returns
the implied $(AssemblyVersion) and $(FileVersion).e.g.:
<Version>1.2.3-beta.4</Version>implies:
<AssemblyVersion>1.2.3</AssemblyVersion>
<FileVersion>1.2.3</FileVersion>Note that if $(AssemblyVersion) or $(FileVersion) are are already set, it
is considered an override of the default inference from $(Version) and they
are left unchanged by this target.
