Cleanup and remove cache attributes

[pergerch]

Setting the Fody ShouldCleanReference property to true will only result in removing the fody references. But our Cache and NoCache attributes will then be "re-referenced" to the Microsoft.Extensions.Caching.Abstractions namespace and will throw a TypeLoadException.

The current workaround is to set the ShouldCleanReference property to false.

Set it back to true and as a cleanup step after weaving, remove our caching attributes from classes and methods, similar to the Fody.Equals add-in:
