  [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.
