feat: add public kvs wrapper target for external consumers

[MOHAMEDELHALOUA]

Add a public :kvs cc_library wrapper target to allow external projects to depend on the KVS library without coupling to internal targets directly. This follows the same pattern as score_communication//score/mw/com:com.

Fixes: external consumers getting visibility errors when depending on :kvs_cpp or :kvsvalue directly.
