Remove deprecated code from phpPass + bigpipe

Not sure what's going on with that migration test.

Added further clean-up of BC as it's unused now

Removal of PhpassHashedPasswordBase::countLog2 and related needs review for BC as it was not deprecated in the base class

Tests are green but also don’t know the policy around protected functions.

We should add an MR to deprecate those things in 10.3 here I think, then we can commit the deprecation and removal in one go - they're just leftovers so it won't make sense to use them with the other changes happening here, but better to keep things in sync.

Added simple CR and 10.3.x branch that deprecates that function.

It probably needs deprecated property trait for the deprecated properties too?

Mean like this?

The Needs Review Queue Bot → tested this issue. It no longer applies to Drupal core. Therefore, this issue status is now "Needs work".

This does not mean that the patch necessarily needs to be re-rolled or the MR rebased. Read the Issue Summary, the issue tags and the latest discussion here to determine what needs to be done.

Consult the Drupal Contributor Guide → to find step-by-step guides for working with issues.

Think the bot is confused because I got a 10.3 MR up also

Self review but looking at others believe got this right

Failure appears to be related to 🐛 Can't log out on translated site in tests - causes issues for 10.3 umami test Fixed

Removed unrelated file and the property is not a service, so properly deprecated it

fixed cs

10.3 is green

Based on the slack thread believe this one is good to go.

Looks good now. Committed/pushed to 11.x and 10.3.x respectively, thanks!
