sculpt: introduce runtime priorities This patch adds 4 priority levels to the runtime subsystem. The highest priority is used for components that are critical for the operation of Sculpt, in particular the Leitzentrale GUI. All regularly deployed components are assigned the lowest priority by default. With priorities available in the runtime subsystem, this patch flattens the priority levels at the top-level init to only two levels and overlays the priority bands of the drivers, leitzentrale, and runtime subsystems into one priority band. This has three benenfits: - This change prevents the starvation of the Leitzentrale GUI from a spinning high-priority driver (issue #3997). - The change will also ease the hosting of latency-critical components in the runtime subsystem that are prioritized higher than regular components, the storage stack, and the network stack. - The Leitzentrale GUI remains always perfectly responsive regardless of the workloads deployed from packages. In the previous version, the runtime graph was sometimes stuttering on high system load. Issue #4045

drivers_managed-pc: simplification This patch removes the former use of ram_fs, fs_rom, and fs_report from the subsystem and uses a report_rom instead. The fs-based reporting was introduced to accommodate automatically instantiated usb_block drivers, which turned out to be impractical for the sculpt scenario.

base: extend PD session with managing_system call Introduce the managing_system privilege for components like the platform_driver to allow it to call system management functionality that is reserved by kernel or special firmware, e.g., ARM Trusted Firmware. The former RAM resource configuration attribute `constrain_phys`, which enabled to constrain the region of physical RAM to be used, gets replaced by the new, broader managing_system configuration attribute of a `start` node. It gets enforced by the sandbox library. Ref #3816

pci_decode: report devices from ACPI info Although we do not have the full ACPI information parsed yet, to announce non-PCI devices derived from the ACPI tables, the device description of the assumed devices is now integral-part of pci_decode. Formerly, the information was gained separatedly as boot-module, whereby we lost synchronization in between ACPI/PCI parsing, BIOS handover, and PS/2 emulation code already acting.
