Skip tensor tests by default in conda recipe to avoid OOM (#2860)

Tensor tests require significant device memory and frequently cause OOM
crashes on internal CI machines during conda package testing (mostly on
Linux) often manifesting as Python abort signals instead of regular
failures.

This PR sets `SKIP_TENSOR_TESTS=1` by default in `conda recipe` test
scripts to avoid such crashes.

Users or CI environments can opt in by setting `SKIP_TENSOR_TESTS=0` on
systems with sufficient memory.
