ci: Add support for triggering test-primops pipelines
This commit adds 4 ways to trigger testing with test-primops.
1. Applying the ~test-primops label to a validate pipeline.
2. A manually triggered job on a validate pipeline
3. A nightly pipeline job
4. A release pipeline job
Fixes #23695

Add test-primops label support
The test-primops CI job requires some additional builds in the
validation pipeline, so we make sure to enable these jobs when
test-primops label is set.

ci: Remove manually triggered test-ci job
This doesn't work on slimmed down pipelines as the needed jobs don't
exist.
If you want to run test-primops then apply the label.

dump-decls: fix "Ambiguous module name"-error
Fixes errors of the following kind, which happen when dump-decls is run on a package that contains a module name that clashes with that of another package.
```
dump-decls: <no location info>: error:
Ambiguous module name `System.Console.ANSI.Types':
it was found in multiple packages:
ansi-terminal-0.11.4 ansi-terminal-types-0.11.5

-{- Note [Aarch64 immediates]
-~~~~~~~~~~~~~~~~~~~~~~~~~~~~
-Aarch64 with it's fixed width instruction encoding uses leftover space for
-immediates.
-If you want the full rundown consult the arch reference document:
-"Arm® Architecture Reference Manual" - "C3.4 Data processing - immediate"
-
-The gist of it is that different instructions allow for different immediate encodings.
-The ones we care about for better code generation are:
-
-* Simple but potentially repeated bit-patterns for logic instructions.
-* 16bit numbers shifted by multiples of 16.
-* 12 bit numbers optionally shifted by 12 bits.
-
-It might seem like the ISA allows for 64bit immediates but this isn't the case.
-Rather there are some instruction aliases which allow for large unencoded immediates
-which will then be transalted to one of the immediate encodings implicitly.
-
-For example mov x1, #0x10000 is allowed but will be assembled to movz x1, #0x1, lsl #16
