templater: start passing resource to read from into _readmapfile()
This patch makes it so we pass in a file-like resource to read from
instead of having `_readmapfile()` open the file. This is one more
step towards making `_readmapfile()` able to read resources opened by
from `importlib.resources`. We still need to pass in the mapfile path
because it's used for loading dependent mapfiles from `%include` and
`__base__`, and it's also used for giving the user better error
messages. Besides that, one can safely call `_readmapfile()` with any
file-like resource after this patch.
