utils: add capability-driven hardware validation helpers

[Srikanth Muppandam (smuppand)]

Summary

Add reusable, capability-driven runtime validation helpers for I2C, PCIe, USB, DeviceTree hardware health, firmware discovery, and QRTR topology.

Key changes

• Discover hardware dynamically through DT, sysfs, modalias, registered drivers, and runtime objects.
• Handle built-in and modular drivers consistently.
• Add actionable diagnostics for unbound devices, missing suppliers, malformed runtime state, and absent optional hardware.
• Add shared inventory helpers for I2C, PCIe, USB host, HID, and mass storage.
• Add PMIC GLINK/UCSI, thermal, regulator, and power-domain validation.
• Add bounded QRTR topology capture and service lookup helpers.
• Allow image-validation suites to disable package recovery with CHECK_DEPS_RECOVER=0.
• Preserve clean SKIP behavior when optional capabilities are not present.

These helpers avoid board- and SoC-specific mappings and provide a reusable foundation for follow-up suite enhancements.
