bitbake: bitbake-setup: replace {THISDIR} token with a keyword: bb-layers-relative

{THISDIR} is a special value token that can be used in the list of enabled
layers to specify the layer location relative to the confguration file:
https://git.openembedded.org/bitbake/commit/?id=b3153be29de8b8570b0c184369bd41f4c646cf92

This replaces the token with an explicit separate keyword for such layers:
so that special processing to determine the final value can be avoided, and
the feature can be formalized in the json schema:

instead of
   "bb-layers": [
        "{THISDIR}/meta-my-project"
    ]

this allows
   "bb-layers-relative": [
        "meta-my-project"

Going forward I think we should strive to avoid any further special value tokens.
