[mlir][python] Support Arbitrary Precision Integers in MLIR C API and Python Bindings (#177733)

This PR extends the MLIR C API and Python bindings to support
**arbitrary-precision integers (`APInt`)**, overcoming the previous
limitation where `IntegerAttr` values were restricted to 64 bits.

Cryptographic applications often require integer types much larger than
standard machine words (e.g., the 256-bit modulus for the BN254 curve).
Previously, attempting to bind these values resulted in truncation or
errors. This PR exposes the underlying word-based `APInt` structure via
the C API and updates the Python bindings to seamlessly handle Python's
arbitrary-precision integers.

SILowerControlFlow removes a basic block which is not removed in the
Post dominator tree.

[clang-tidy] Add llvm-use-vector-utils (#177722)

This new check suggests the following replacements:
* `llvm::to_vector(llvm::map_range(X, Fn))` -> `llvm::map_to_vector(X,
Fn)`
* `llvm::to_vector(llvm::make_filter_range(X, Fn))` ->
`llvm::filter_to_vector(X, Fn)`
and add the `SmallVectorExtras.h` include when necessary.

The check is called `vector-utils` because we may want to handle more
cases in the future, like turning explicit calls to SmallVector
constructor to `llvm::to_vector` (which lives in `SmallVector.h`, not
`SmallVectorExtras.h`).

This PR preserves leading dimensions for

operations which have impact on shapes:
broadcast/multi-reduction/shape_cast/transpose.
Rank-sensitive operations are operations whose semantics depend on the
tensor rank (and consequently its shape), and therefore must not alter
the input tile rank or shape, such as by dropping leading dimensions.
