feat: Introduce TableCreationConfig for table creation property handling

1. Adds the ability to explicitly enable table features via table properties
using the delta.feature.<featureName> = supported syntax, matching the
Java Kernel's behavior. Only ALLOWED_DELTA_FEATURES can be set during
create. Features get added to protocol features.

2. Allows the min reader/ writer versions to be updated in the protocol using
signal flags. Only protocol versions (3, 7) are supported.

Key Changes:
- Add SET_TABLE_FEATURE_SUPPORTED_PREFIX and SET_TABLE_FEATURE_SUPPORTED_VALUE
  constants to table_features module. Move the feature/ property allow/
  deny list to the table property configuration module
- Add TableFeature::from_name() to parse feature names from strings
- Add TableFeature::is_reader_writer() to check feature type
- Add TableCreationConfig struct to encapsulate parsing and validation of
user-provided table properties during CREATE TABLE operations.
- Extract delta.feature.* signal flags into reader/writer feature lists
- Extract delta.minReaderVersion/minWriterVersion into protocol hints
- Strip signal flags from properties, pass remaining to metadata
- Reject unknown features and invalid feature flag values

Usage:
create_table("/path/to/table", schema, "MyApp/1.0")
    .with_table_properties([
        ("delta.minReaderVersion", "3"),
        ("delta.minWriterVersion", "7"),
    ])
    .build(&engine, Box::new(FileSystemCommitter::new()))?
    .commit(&engine)?;

The delta.feature.* properties are consumed during build() and not stored
in the final Metadata configuration, matching Java Kernel behavior.
