LightningCLI instantiator receives values applied by instantiation links to set in hparams

[mauvilsa]

What does this PR do?

Fixes save_hyperparameters when used through LightningCLI (feature introduced in #18105) so that target values of links applied for instantiation are included in hparams.

Fixes #20311
Fixes #20147

Also adds an official way to disable #18105 (parameter load_from_checkpoint_support), which might be desired by some people, e.g #20432, #20726

Looking at the logs, in Install package & dependencies I see that jsonargparse v4.35.0 gets installed (e.g. here), even though the requirement is >=4.39.0, <4.40.0. I don't know how to figure out why this is happening.

not sure why, but we added this silly line:
