ci: use static+shared builds to cut number of cmake jobs (#865)

With CMake builds supporting static-shared libssh2 builds in a single
pass, we no longer need to run static and shared jobs separately. For
the same effect it's enough to run builds with both shared and static
builds enabled. Halving CI jobs.

We add an extra run to test the CMake config-path without shared builds
enabled.

This allows to add useful jobs, e.g. MSVS 2022 or ZLIB-enabled builds
for Windows, valgrind builds or other useful stuff, without stretching
CI run times further.
