debug: Add BTF_WITH_CORE_DEBUG debug format

To best handle BTF/CO-RE in GCC, a distinct BTF_WITH_CORE_DEBUG debug format is
being added.  This helps the compiler detect whether BTF with CO-RE relocations
needs to be emitted.

gcc/ChangeLog:

	* flag-types.h (enum debug_info_type): Add new enum
	DINFO_TYPE_BTF_WITH_CORE.
	(BTF_WITH_CORE_DEBUG): New bitmask.
	* flags.h (btf_with_core_debuginfo_p): New declaration.
	* opts.c (btf_with_core_debuginfo_p): New definition.
