Add types for activejob v8.1

[amatsuda]

Adds signatures for activejob 8.1, based on 8.1.4.

The latest version in this repository was activejob 6.0, whose generated file came from Rails 6.0. Like the other Rails 8.1 gems (#1084, #1086, #1087), this PR regenerates the RBS from the 8.1.4 source and carries over the hand-written parts.

How it is made

activejob-generated.rbs comes from rbs prototype rb run on lib, then post-processed the same way as the other Rails 8.1 gems:

• Drop members that core, dependencies, or the hand-written RBS already define
• Fill missing type arguments of generic classes with untyped
• Drop mixins and superclasses that can't be resolved
• Add accessors defined with class_attribute, mattr_accessor, and cattr_accessor, and methods defined with delegate. A cattr_accessor inside included do ... end goes to the class that includes the concern, like class_attribute
• Carry over typed signatures from 6.0 where the method still has the same parameters (6)

The job generator in lib/rails is left out, since its superclass comes from railties, which activejob doesn't depend on.

Changes to the hand-written RBS

The first commit copies 6.0's hand-written files unchanged, so the following commits show only the 8.1-specific changes:

• Remove the fake Que::Job and SuckerPunch::Job. Rails no longer has those adapters
• Add logger and log_arguments to ActiveJob::Base. Logging defines them in its included block
• ActiveJob::Base extends ActiveSupport::Callbacks::ClassMethods and ActiveSupport::Rescuable::ClassMethods, so jobs have rescue_from

Return types

job_id, arguments, executions, exception_executions, queue_name, priority, locale, timezone, enqueued_at, enqueue_error, and enqueue/perform_later, which return the job, or false if it couldn't be enqueued.

Optional blocks

rbs prototype marks a &block param as required unless the body checks it. All required blocks were checked against the source, and the 14 that only forward the block or don't use it were made optional: for example, before_perform :method_name, and assert_no_enqueued_jobs without a block.

Tests

Each commit that changes types adds tests that fail without it. bin/test gems/activejob/8.1 and RuboCop's strict cops pass on every commit from the generation commit onward.

The existing gems that depend on activejob (actionmailer 7.0, actiontext 7.2, and activestorage 7.0) still resolve to activejob 6.0, and their tests pass.
