[OE-core] [PATCH 3/6] csl-versions.inc: capture version in signatures

[Christopher Larson]

We want to ensure that changing external toolchain version will change the
metadata checksums of target recipes. This will do so via ensuring that any
variable which references TOOLCHAIN_OPTIONS also pulls in the toolchain
version variables.
