docs/manual: enhance doc for BR2_TOOLCHAIN_HEADERS_AT_LEAST_X_Y

The BR2_TOOLCHAIN_HEADERS_AT_LEAST_X_Y symbols can be used to denote the
lowest required kernel headers version, but also the highest supported
version. Document that.

Use the `...` construct instead of +...+ used eveywhere else, otherwise
asciidoc would render +<=+ to the ⇐ arrow, while `...` does no rendering
at all.
