[PATCH 4/5] lib/Kconfig.debug: Use CONFIG_PAHOLE_VERSION

From: Nathan Chancellor <nathan@kernel.org>

Now that CONFIG_PAHOLE_VERSION exists, use it in the definition of
CONFIG_PAHOLE_HAS_SPLIT_BTF and CONFIG_PAHOLE_HAS_BTF_TAG to reduce the
amount of duplication across the tree.

+ Decide whether pahole emits btf_tag attributes (btf_type_tag and
+ btf_decl_tag) or not. Currently only clang compiler implements
+ these attributes, so make the config depend on CC_IS_CLANG.
