bpf, kconfig: Add consolidated menu entry for bpf with core options
Right now, all core BPF related options are scattered in different Kconfig

subsystem entry under ...
General setup --->
BPF subsystem --->
... in order to have all knobs in a single location and thus ease BPF related
configuration. Networking related bits such as sockmap are out of scope for
the general setup and therefore better suited to remain in net/Kconfig.
