soc/intel/common: Add Kconfig to enable compression on ME_RW blobs
Add SOC_INTEL_CSE_LITE_COMPRESS_ME_RW Kconfig to enable compression on
ME_RW blobs. Select the Kconfig to add LZMA compressed ME_RW blobs to
ME_RW_A/B regions.
On ADL-N, this results in savings of ~665KB in each of ME_RW_A/B
regions.
