[Enhancement] limit tablet write request size (backport #50302)

[mergify]

Why I'm doing:

When there are large chunks during the load process, the following error may be returned due to exceeding the size limit of protobuf.

NodeChannel currently only aggregates batches based on the function of the chunk, but does not take into account the size of the chunk.

What I'm doing:

In this PR, I have added chunk mem usage check to avoid generating large pb requests for load tasks

Fixes #issue
