Bump IREE to latest commit on main.

[ScottTodd]

We're approaching our 3.1.0 release across all IREE packages, so bumping to build/test closer to HEAD.

PR #721 updates to the latest nightly, but we can also update to the latest commit, which includes multiple changes to https://github.com/iree-org/iree/tree/main/runtime/src/iree/hal/drivers/hip that we should test soon.

Commit range relative to #721: iree-org/iree@iree-3.1.0rc20241220...0a0483e

From these logs: https://github.com/nod-ai/shark-ai/actions/runs/12439009356/job/34732288777?pr=722#step:7:253, these errors:

ERROR tests/apps/sd/e2e_test.py::test_sd_server - RuntimeError: Timeout waiting for server start
ERROR tests/apps/sd/e2e_test.py::test_sd_server_bs4_dense - RuntimeError: Timeout waiting for server start
ERROR tests/apps/sd/e2e_test.py::test_sd_server_bs8_percall - RuntimeError: Timeout waiting for server start
ERROR tests/apps/sd/e2e_test.py::test_sd_server_bs4_dense_fpd2 - RuntimeError: Timeout waiting for server start
ERROR tests/apps/sd/e2e_test.py::test_sd_server_bs8_dense_fpd8 - RuntimeError: Timeout waiting for server start

seem to be new regressions, but I would expect more helpful error output, ideally from a unit test.

FYI @AWoloszyn @MaheshRavishankar . The only new IREE commits here are from both of you. Maybe the test failures make more sense to one of you 🤷
