Backmerging Module Federation v2 #18809

Feature request

This is a tracking issue for various pieces of work to backmerge some of the advances in module federation 2 back into webpack core.

• Reference Hoisting: Single Runtime Chunk breaks Module Federation Container init #18810
• Remove Mandatory import() + support splitChunks: all: Remove Need for Async Import in Module Federation  #18812

What is the expected behavior?

What is motivation or use case for adding/changing the behavior?
I want to sync these changes into rspack and want to reduce the number of patches i must maintain in my plugin that fix "bugs in webpack"

How should this be implemented in your opinion?
TBD

Are you willing to work on this yourself?
yes, but I will need contributor help - i have taken it about as far as i know how to.
