pgsql: meson: ecpg: Split definition of static and shared libraries

meson: ecpg: Split definition of static and shared libraries

Required for correct resource file generation, as the resource files should
only be added to the shared library.

This also fixes a bunch of issues in the .pc files.

Previously I tried to avoid building sources twice, once for the static and
once for the shared libraries. We could still do so, but it's not clear that
it's worth the complication.
