Integrates/llvm@91339fd (#24153)

- Add missing BufferizableOpInterface methods to DispatchTensorLoadOp.
Due to https://github.com/llvm/llvm-project/pull/189073 changed One-Shot
Analysis, module bufferize, and SCF bufferization to use TensorLikeType
instead of TensorType.
- Upgrade to Bazel 8.6.0 to align with LLVM. As
https://github.com/llvm/llvm-project/pull/192518 bumped rules_python
from 1.6.3 to 1.9.0
