feat: make Logging property for GraphQLApi

[pradrx]

Issue #, if available

Description of changes

Created new property Logging in Serverless::GraphQLApi resource, which allows customers to specify their logging implementation in the SAM template.

Maps to the LogConfig property of the AppSync::GraphQLApi resource. Includes defaults for 2 properties:

• CloudWatchLogsRoleArn: If not defined, creates a role with an AWS managed AppSync CloudWatch policy and attaches to the GraphQLApi resource.
• FieldLogLevel: Defaults to ALL.

This change also includes a small refactor of the error transform tests for GraphQLApi, bundling them all in error_graphqlapi.yaml.

Description of how you validated changes

Modified and created transform tests to work with Logging property.

Overall looks good. Just some nit comments.

The most recent commits should address the majority of comments that were focused on type checking and reducing branching.

I separated the logic for when Logging property is a boolean type or a dictionary type, so they now have two separate functions: create_logging_default() and parse_logging_properties().

This reduced the nested if branches and repeated type checks, and also separates the logic in what should be a more readable manner.
