Add shared runtime inventory and validation primitives for I2C, PCIe, USB, device-tree health, firmware discovery, and QRTR topology. Keep capability detection dynamic across platforms and expose bounded diagnostics for consumer suites. Signed-off-by: Srikanth Muppandam <smuppand@qti.qualcomm.com>

Correlate enabled I2C controllers, runtime adapters, DT clients, alias-resolved driver support, and actual bindings without board-specific mappings. Preserve the optional legacy path and print per-object diagnostics for malformed or unbound clients. Add distro-aware i2c-tools recovery for supported host distributions, read-only adapter capability checks, and explicitly requested address scan, register read, and transactional write-and-restore operations with bounded execution and validation.

Summary
Enhance the Buses suite with capability-driven I2C validation across Qualcomm Linux platforms without relying on static board, SoC, adapter, or driver mappings.
Depends on the platform runtime foundation PR.
