Improve generation of pkg-config files for static only libraries.

Previously pkg-config files generated by the pkgconfig modules for static libraries
with dependencies could only be used in a dependencies with `static: true`.

This was caused by the dependencies only appearing in Libs.private even
if they are needed in the default linking mode. But a user of a
dependency should not have to know if the default linking mode is static
or dynamic; A dependency('somelib') call should always pull in all
needed pieces into the build.

Now for meson build static libraries passed via `libraries` to the generate
method automatically promote dependencies to public.
