[Bump] tvm-ffi to 59da4c0

Bumps 3rdparty/tvm-ffi from 98d0029 to 59da4c0, picking up seven
commits from apache/tvm-ffi:

• [FEAT] Optimize Expected for minimal compiled code and efficiency (failed to load the Compile library  #599)
• [FEAT] Streamline AccessPath/AccessStep print format (vgg16 workload (1, 128, 122, 128, 3, 1, 1) error fixed and added to topi test #598)
• [CI] Use uv tool run for sdist build instead of pipx (How to load params in C++ deploy? #600)
• [CORE] Make AnyView trivially copyable — match C-ABI struct passing (failed to call a env compiler(gcc) to create a shared library. #602)
• feat(python): add tensor methods to align with C++ APIs (TVMError: [11:28:52] E:\Git_sources\TVM\tvm\src\runtime\c_runtime_api.cc:83: Check failed: allow_missing Device API gpu is not enabled. #604)
• [FIX] Drop test_empty_tensor_attributes (numpy dlpack stride change) (Question: How to import .ptx file into the example (tvm/apps/howto_deploy) ? #607)
• [TEST] Relax test_shared_dag_hash_scaling_not_exponential ratio to 4x (What is the Relationship Between tvm, nnvm and nnvm compiler? #612)

The bump range is additive for almost all of the above (performance
improvements to Expected, new Python tensor methods, AnyView ABI
alignment, CI toolchain switch). One commit required a TVM-side
migration:

apache/tvm-ffi#598 moved the __ffi_repr__ hooks for
ffi::reflection::AccessPath and AccessStep into tvm-ffi itself
(src/ffi/extra/reflection_extra.cc, compiled into libtvm_ffi.so).
TVM already registered the same hooks in src/ir/access_path_repr.cc,
causing a double-registration abort at library load time. This commit
removes the duplicate AccessPath/AccessStep __ffi_repr__ registrations
from access_path_repr.cc, keeping only the node.AsRepr global function
that tvm-ffi does not provide. The format emitted by tvm-ffi's hooks is
equivalent for common cases; missing-item steps now use the
[<missing:...>] notation from tvm-ffi rather than the ...? suffix
that TVM used previously.

Code Review

This pull request updates the 3rdparty/tvm-ffi subproject commit to 59da4c0b82af0d499dae34bd89ef010f64d3ff45. Consequently, duplicate registrations of __ffi_repr__ hooks for ffi::reflection::AccessPath and AccessStep in src/ir/access_path_repr.cc have been removed, as they are now handled directly by tvm-ffi to prevent double-registration aborts at library load time. Unused headers and stream inclusions were also cleaned up. There are no review comments, and I have no additional feedback to provide.
