feat(DAT-18853): Add custom diff change generator for Databricks

[filipelautert]

• Added ChangedTableChangeGeneratorDatabricks class to handle Databricks-specific table property changes.
• Implemented logic to compare and generate changes for table properties.
• Updated META-INF/services/liquibase.diff.output.changelog.ChangeGenerator to include the new change generator.

@KushnirykOleh any idea on how to add tests here?

[KushnirykOleh]

diff-changelog test from test-harness doesn't work properly in extensions. To check parsing I would only add unit test with Strings that looks like these

liquibase-databricks/src/test/resources/liquibase/harness/change/expectedSnapshot/databricks/createTable.json

Lines 7 to 16 in 2cd2f40

	"name": "test_table",
	"tblProperties" : "'delta.checkpoint.writeStatsAsJson'='false', 'delta.checkpoint.writeStatsAsStruct'='true', 'delta.columnMapping.maxColumnId'='2', 'delta.columnMapping.mode'='name', 'delta.enableDeletionVectors'='true', 'delta.feature.allowColumnDefaults'='supported', 'delta.feature.columnMapping'='supported', 'delta.feature.deletionVectors'='supported', 'delta.feature.invariants'='supported', 'delta.minReaderVersion'='3', 'delta.minWriterVersion'='7'"
	}
	},
	{
	"table": {
	"name": "test_table_properties",
	"Location" : "s3://databricks-th/test_table_properties",
	"tblProperties" : "'delta.checkpoint.writeStatsAsJson'='false', 'delta.checkpoint.writeStatsAsStruct'='true', 'delta.enableDeletionVectors'='true', 'delta.feature.deletionVectors'='supported', 'delta.feature.invariants'='supported', 'delta.minReaderVersion'='3', 'delta.minWriterVersion'='7', 'this.is.my.key'='12', 'this.is.my.key2'='true'"
	}

- actual tblProperties returned from databricks

Thanks!
