Mirror wattson_soc_model.proto and FrameworksBaseTracePacket extension 1004 from Android frameworks/base. Define storage tables for dynamic Wattson SoC power models (device info, CPU topology, idle state mapping, and subsystem power curves) via the table generator DSL, and register them in TraceStorage.
Implement WattsonSocModelModule to decode WattsonSocModel packets (TracePacket tag 1004) into Wattson custom storage tables. Decodes structured WattsonCpuTopology (mapping physical cores to cpufreq policies, applying deep idle offsets, and setting 2D frequency voting) and subsystem power curves (1D/2D CPU, GPU, L3, TPU) with backward compatibility fallbacks. Adds comprehensive unit tests.
Route dynamically imported Wattson SoC models from storage tables into Wattson SQL stdlib pipeline. Assigns highest priority to custom device models in _wattson_device_map, and merges custom topology and empirical power curves with in-tree tables using UNION ALL. All downstream power estimations and UI continuous tracks function seamlessly for both in-tree and out-of-tree devices.

This PR introduces end-to-end support for dynamic out-of-tree (OOT) Wattson SoC power models. Trace Processor can now ingest SoC power models directly embedded in trace packets (
WattsonSocModel, field 1004 ofFrameworksBaseTracePacket) without requiring device models and power curves to be hardcoded in upstream Perfetto stdlib.
