buildtools/chkincs: check SDK headers for C++ compatibility

With a one-line change to the lib meson.build file we can add the SDK
headers to the list of files to be checked using the chkincs binary.
Unfortunately, many of those SDK header depend upon headers in the PCI
and vdev bus drivers, so we need to update chkincs build to ensure those
dependencies are added. We also need to allow internal APIs to be
present in these SDK headers.
