Previously we had a big switch on Op kind to decide how to lower a given
JIT operator to NNC. This PR changes this switch to a hash table lookup.
Why? This helps us with at least two things:
1) With this approach we can easily check if we know how to handle a
given node in advance - i.e. we can inspect the entire graph and tell
whether it's possible to compile it or not without actually trying to do
that and dying in the middle. This would allow us to, say, provide
user-friendly error messages in AOT workflow.
2) We can switch to use schema instead of op kind to determine correct
lowering. Unlike op schema, op kind might be ambigous (see e.g. #64963)
and using it instead of schema can lead to bugs.

BufHandle has exactly the same functionality and should be used instead.

Now that there is no classes using KernelArena for memory management we
can remove it.

This is another commit in transition from KernelArena memory management.
Tensor is essentially just a pair of <BufPtr, StmtPtr> and we don't need
to dynamically allocate it at all - it's cheap to pass it by value, and
that's what we're switching to in this commit.
After this change nothing uses KernelScope/KernelArena and they can be
safely removed.

Whatever gcc version OSS Bazel uses wasn't happy move-constructing the
SimpleIREvaluator, so use a unique_ptr instead.
Test Plan:
CI. Hope that the gcc version used by OSS Bazel build is
happier with this (it should be), since actually testing it locally is
an intractable pain.
