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.

Fixes #18324 #23147 #20020
Expands do notation before typechecking using `HsExpansion`
- Adds testcases T18324, T18324b, DoubleMatch
Expands
- Do statements
- Monadic do statements
- monadic fix blocks
- make sure fail is used for pattern match failures in bind statments
- Makes sure unused binds generate warnings
- runs the pattern match check in generated lambda exprs to avoid getting suprious pattern match failures. c.f. pmcheck/should_compile/DoubleMatch.hs
- PopSrcSpan in HsExpr to pop error context
- Discards default monad fail alternatives that are spuriously generated
- Make sure we check for generated loc span for checking if the (>>) is user written or expanded for /do/ purposes

- Add PopSrcSpan (XXExprGhcRn) in appropriate places while expanding statements
- correct source spans displayed for warnDiscardedDoBindings
- use `mkExpandStmt` to store original stmts along with expanded expr for using the right context for error message printing
- improves error messages for applicative do
- remove special case from isMatchContextPmChecked (long distance info is now properly propogated)
- set correct src spans to statement expansions
- Match ctxt while type checking HsLam is different if the lambda match is due to an expression generated from a do block
- call tcExpr and not tcApp in PopSrcSpan so make sure impredicativity works fine
- look into XExprs in tcInferAppHead_maybe for infering the type to make T18324 typecheck and run

- make the ExpandedStmt generated expression location-less
- Introduce ExpansionStmt for proper `hsSplitApps`
- Introduce `VAExpansionStmt` that is just like `VAExpansion` but for statements
- Aligning expand stmt context pushing on error stack.
- Pop error context while checking do expansion generated GRHSs inside HsLam so that we do not print the previous statement error context
- makes template haskell happy
- some fix for let expansions
- refactor tcExpr into tcExpr and tcXExpr
- adding Note and references
- make monad fail errors normal again

Generated Origin now carries HsStmtContext so that we don't have to recreate it
