Parquet: Fix decimal and UUID filter pushdown conversion

[alexandrefimov]

This fixes Parquet filter pushdown conversion for decimal and UUID predicates.

Changes:

• Use the Parquet MessageType when building the pushed Parquet filter so decimal predicates use the actual physical primitive type.
• Convert decimal literals for INT32, INT64, BINARY, and FIXED_LEN_BYTE_ARRAY encodings.
• Use the actual fixed-length byte array length for fixed decimal predicates.
• Fall back to NOOP when decimal literals cannot be represented safely at the file schema scale/precision.
• Convert Parquet UUID logical type back to Iceberg UUIDType so UUID predicates bind correctly.

Tests:

• ./gradlew :iceberg-parquet:spotlessCheck :iceberg-parquet:test

Closes #16035

This is ready for review.

For context, this picks up the work from #16051, which was closed as stale.
Thanks @laserninja for the original report and PR.

This version keeps the same issue scope but also uses the Parquet physical type when converting decimal literals, covers INT32/INT64/BINARY/FIXED_LEN_BYTE_ARRAY decimal encodings, and adds UUID logical type conversion coverage.
