Remove ircmaxell/password-compat

Problem/Motivation

It is not clear why we have a reference to ircmaxell/password-compat in our composer.lock file. I suppose it was required at one point and since we update everything one at a time, this got left in there. There is no reference or dependency to this package anywhere except one lone entry in composer.lock.

~/w/d/drupal   8.8.x *… > composer why ircmaxell/password-compat There is no installed package depending on "ircmaxell/password-compat"

This was found while working on #3079791: Bump Drupal's minimum PHP version to 7.2 as soon as 9.0.x is branched (a higher version may be required later). See comment 26 in that issue.

Proposed resolution

Remove the reference to the package. Running composer update removes it automatically but that doesn't help us. composer remove ircmaxell/password-compat reports a warning but removes the package.

Remaining tasks

- Decide if this is not required and if it is the correct approach.

User interface changes

None

API changes

The forward compatibility layer won't be available anymore but that doesn't matter because these functions exist in PHP since 5.5.

Data model changes

None

Release notes snippet
