[core] Support options in ObjectTable

[shyjsarah]

Purpose

Previously, ObjectTable did not support storing and passing options — its options() method always returned an empty map, and copy() ignored dynamic options entirely. This was inconsistent with other table types like FormatTable, LanceTable, and IcebergTable, which all properly support options.

This PR adds options support to ObjectTable, aligning it with other table type implementations.

Tests

Modified RESTCatalogTest#testObjectTable to verify:

• Custom options set during table creation are preserved and accessible via options()
• copy() correctly merges dynamic options with existing options
• copy() can override existing option values
• copy() does not modify the original table's options
