[Feature Request] Re-enable sharding checks for test_vector_conversion.cpp.

[jjiangTT]

Is your feature request related to a problem? Please describe.
Re-enable additional sharding checks in test_vector_conversion.cpp.

Describe the solution you'd like
Sharding checks for sharding along height, width, and block currently fail with the shard_spec given in get_tensor_spec_with_memory(). New shard_specs compatible with these modes need to be written for these tests to work fully.

Describe alternatives you've considered
These three test suites have been disabled for now until a fix can be implemented. A square case that potentially checks out with sharding along all of these dimensions could be used as the shard_spec as well and can be explored.

Additional context
Interleaved and single-bank sharding still work.
