Currently the set-target has sdkconfig file name hardcoded to the
default one and doesn't honor custom config paths or names.
IMHO the only place where we can really now the config file name
is in cmake. But also the config should be really renamed only if
the set-target action is running.
This moves the config file renaming into cmake and it's performed only
when _IDF_PY_SET_TARGET_ACTION env. var. is set to 'ON'. This should
hopefully guarantee that it's really renamed only while set-target is
running.
