Introduce dependency parameter cpp.linkWholeArchive

Maps to --whole-archive, -force_load and /WHOLEARCHIVE on the toolchain
level.

[ChangeLog][Parameters] When pulling in static library products, the new
Depends parameter cpp.linkWholeArchive can now be specified to force all
the library's objects into the target binary.
