abseil-cpp: Split so-files into separate packages

Use PACKAGES_DYNAMIC and PACKAGESPLITFUNCS to put each shared object
into its own package named libabsl-*.
The shared objects depend on each other which means you still get a
lot of them if you link against a single one.

The main package abseil-cpp RDEPENDS on all of the libabsl-* packages.
