Implement interceptors for mem* and str* functions

[fmoessbauer]

Currently, memory that is manipulated using these functions is either out-of-scope, or leads to many false-positives. To counter this, it's better to not instrument the implementation of these functions, but to intercept them and feed the processed data directly into the detector.

Be aware, just wrapping the exported symbols in ucrtbase, kernel, etc. is not sufficient, as some parts are directly inlined into the application, or aliased, or dispatched to specific implementations.
