Add the GUC `timescaledb.hypercore_use_access_method` for dealing with the default value to use for functions accepting the `hypercore_use_access_method` parameter (`compress_chunk`, `add_compression_policy`, etc.) Value can be "on" (use the hypercore access method) or "off" (do not use the hypercore access method) and can be overridden by the parameter to the functions by explicitly providing a value. If no value is chosen, the default will be picked. Make GUC a boolean instead
