Description
Forked from #1029
a) A very convenient, and standard, way to configure tools' cache location is to set $XDG_CACHE_DIR. Many of my project's fixtures do this for other reasons already. Similarly, the most convenient, and standard, way to set "basetmp" would be $TMPDIR.
b) "something a CI system can easily pick up" is exactly these environment variables. Many systems will already support this, and those that don't will support injecting environment variables.
c) "non-containered ci" will either support ~/.cache correctly, or set $XDG_CACHE_DIR, because this is necessary for other tools that use the standard. Again, this is already handled in many of my projects because of other tools.

Research direction
Start by reading the discussion in #1029 and this issue's comments to establish the intended behavior for XDG_CACHE_DIR and TMPDIR. Trace pytest's existing cache and temporary-directory entry points, then verify the behavior in CI-like environments; done means those environment variables configure the relevant locations consistently.
