soc/intel/meteorlake: Consolidate settings for enabling tracehub
To get tracehub working, it requires few settings such as
SOC_INTEL_METEORLAKE_DEBUG_CONSENT=2 and enable tracehub device in
dev tree. This commit binds all tracehub related settings to Kconfig,
so that users only need to enable SOC_INTEL_COMMON_BLOCK_TRACEHUB
TEST=boot on screebo and test tracehub device exists and working
