* test: trim CI runtime for slow Python suites * remove useless test * Update TVM submodule to latest commit and remove manual device assert test from CI. Replace with a call to tilelang.testing.main(). * lint fix * fix * revert test for eager jit --------- Co-authored-by: Zhiwen Mo <zm125@ic.ac.uk>
