[improve][broker] Add dedicated partition configuration for system topics to reduce resource usage

[zjxxzjwang]

Motivation

The number of partitions for creating system topics depends on the value of the "defaultNumPartitions" configuration field, but this field is also the number of partitions for automatically creating topics. If the value of defaultNumPartitions is set to a large value, the system theme partition is also large, causing resource waste.

Modifications

New "systemTopicDefaultNumPartitions" configuration field, isolation system topic creation and automatically create topic for "defaultNumPartitions" fields of mutual dependence. When metadata is mounted, the system topic and common topic depend on the default partition configuration parameters
