[improve][fn] Provide a way to set Pulsar client memory limit in Pulsar Function

[walkinggo]

Main Issue: #23723

Motivation

see #23723 . The main work of this PR is to add a method for setting the memory limit of the Pulsar client in a Pulsar Function.

Modifications

1.Memory Limit Support:
Added MemoryLimit class to define memory constraints for Pulsar clients, which includes both an absolute value and a percentage of the maximum direct memory.
This memory configuration is applied across several components including FunctionConfig, WorkerConfig, InstanceConfig, and ThreadRuntimeFactory.
2.Class Updates:
Introduced new fields in configuration classes such as FunctionConfig, WorkerConfig, and InstanceConfig to hold memory limit settings.
Updated ThreadRuntimeFactory to handle the memory limit during initialization, ensuring that the client memory limit is respected.
3.Proto File Changes:
Updated Function.proto to include a new MemoryLimit field, allowing the configuration of memory limits directly via function details.
