Reland "Revert "Reland "Allow sending to separate payload types for each simulcast index."""

This is a reland of commit Ife7d43471c85fdea9bd26cc982bce410c0d75527

In the previous implementation, there was an issue where switching codecs
with VideoEncoderSelector would cause a crash, so I have fixed it.
Specifically, if there are no changes to params.send_codecs, I now remove
all parameters related to mixed-codec simulcast.
This should ensure that when an unintended codec switch occurs,
the behavior remains the same as before.

Additionally, I have added a test to reproduce this crash issue.
I confirmed that the issue occurred in the previous implementation and
that it does not occur in the current implementation.
