Jeremy Compostella 78295974f8 soc/intel/common: Add feature directory for SoC-specific common code
Introduce a new directory structure src/soc/intel/common/feature/ for
sharing SoC-specific code across Intel SoC generations to reduce code
duplication.

Unlike the common block code (src/soc/intel/common/block/) which is
intended for reusable IP blocks, the feature code is for SoC-specific
functionality that is similar (but not identical) across multiple
generations. Platform-specific differences are handled through
configuration options or platform-specific macros.

This commit:
- Creates src/soc/intel/common/feature/ directory
- Adds feature/Kconfig defining SOC_INTEL_COMMON_FEATURE
- Adds feature/Makefile.mk to build subdirectories
- Updates src/soc/intel/common/Kconfig.common to source feature/Kconfig
- Updates src/soc/intel/common/Makefile.mk to include feature/ subdirs
- Documents the common code directory structure in
  Documentation/soc/intel/code_development_model/code_development_model.md
