hle: add process identity metadata for application services

Introduce explicit process identity metadata for loaded programs and expose PID-based lookup helpers from the process loader. This lets HLE services resolve title metadata from the calling process instead of relying on the global active application.
Also log disk cache initialization with PID, title ID, display version, selector, and enabled state so cache ownership is visible.
