[perf-db][SQLite] Support tensor casting and non-packed tensors

[atamazov]

Originated from:

• Add typecast to config key #2413 (comment)
• Reference kernel for 3D convolution for non-packed tensors #2334 (comment)

This is not urgent for now, because existing solvers that can handle tensor casting or non-packed tensors are not tunable, but as soon as we have the first tunable solver this enhancement will turn into a blocker bug.
