templatekw: add {size} keyword as an example of fctx-based keyword

I'll add {status}, and I think some lfs keywords can be migrated to this.
I'm not certain how many fctx-based keywords will be introduced into the
global space, but if there are a couple more, we'll probably need to sort
them out to the "File Keywords" section in the templater help. Until then,
fctx keywords are hidden as experimental.
