Merge LinkAssemblies and StripEmbeddedLibraries tasks #1092

An idea: it might be possible to improve build time by implementing striping the embedded libraries as linker step. We already load all the assemblies in the linker, so we might just strip them at the same time as well.

Expected Behavior

Strip embedded libraries in the linker. Possibly faster build times.

Actual Behavior

Stripping of embedded libraries is done as a separate target/task.
