fix(carto): Add missing 'client' parameter to query requests

[donmccurdy]

Adds missing 'client' parameter to query requests from the @deck.gl/carto module.

Comments:

• I've added client: DEFAULT_CLIENT to DEFAULT_PARAMETERS in common.ts. This is slightly redundant, as base-source.ts also defines it in SOURCE_DEFAULTS, but I see no harm in having both.
• In basemap.ts we make some queries directly with fetch(), without these parameters. I'm not sure whether the parameters are expected, in that case.

@donmccurdy I think it is better to pass the clientId via the same method we use in the data sources, to allow the application to customize it. I've updated the code & added a missing test for query()
