Change WarningWithFlag to plural WarningWithFlags
Resolves #22825
Now each diagnostic can name multiple different warning flags for its reason.
There is currently one use case: missing signatures.
Currently we need to check which warning flags are enabled when
generating the diagnostic, which is against the declarative nature of
the diagnostic framework.
This patch allows a warning diagnostic to have multiple warning flags,
which makes setup more declarative.
The WarningWithFlag pattern synonym is added for backwards compatibility
The 'msgEnvReason' field is added to MsgEnvelope to store the
`ResolvedDiagnosticReason`, which accounts for the enabled flags, and
then that is used for pretty printing the diagnostic.

Configure -Qunused-arguments instead of hardcoding it
When GHC invokes clang, it currently passes -Qunused-arguments to
discard warnings resulting from GHC using multiple options that aren't
used.
In this commit, we configure -Qunused-arguments into the Cc options
instead of checking if the compiler is clang at runtime and hardcoding
the flag into GHC.
This is part of the effort to centralise toolchain information in
toolchain target files at configure time with the end goal of a runtime
retargetable GHC.
This also means we don't need to call getCompilerInfo ever, which
improves performance considerably (see !10589).

Don't suggest `DeriveAnyClass` when instance can't be derived.
Fixes #19692.
Prototypical cases:
class C1 a where
x1 :: a -> Int
data G1 = G1 deriving C1
class C2 a where
x2 :: a -> Int
x2 _ = 0
data G2 = G2 deriving C2
Both of these used to give this suggestion, but for C1 the suggestion
would have failed (generated code with undefined methods, which compiles
but warns). Now C2 still gives the suggestion but C1 doesn't.

Add standalone kind signatures for Code and TExp
CodeQ and TExpQ already had standalone kind signatures
even before this change:
type TExpQ :: TYPE r -> Kind.Type
type CodeQ :: TYPE r -> Kind.Type
Now Code and TExp have signatures too:
type TExp :: TYPE r -> Kind.Type
type Code :: (Kind.Type -> Kind.Type) -> TYPE r -> Kind.Type
This is a stylistic change.

Implement the -Wimplicit-rhs-quantification warning (#23510)
GHC Proposal #425 "Invisible binders in type declarations" forbids
implicit quantification of type variables that occur free on the
right-hand side of a type synonym but are not mentioned on the left-hand side.
The users are expected to rewrite this using invisible binders:
type T1 :: forall a . Maybe a
type T1 = 'Nothing :: Maybe a -- old
type T1 @a = 'Nothing :: Maybe a -- new
Since the @k-binders are a new feature, we need to wait for three releases
before we require the use of the new syntax. In the meantime, we ought to
provide users with a new warning, -Wimplicit-rhs-quantification, that would
detect when such implicit quantification takes place, and include it in -Wcompat.

Check visibility of nested foralls in can_eq_nc (#18863)
Prior to this change, `can_eq_nc` checked the visibility of the
outermost layer of foralls:
forall a. forall b. forall c. phi1
forall x. forall y. forall z. phi2
^^
up to here
Then it delegated the rest of the work to `can_eq_nc_forall`, which
split off all foralls:
forall a. forall b. forall c. phi1
forall x. forall y. forall z. phi2
^^
up to here
This meant that some visibility flags were completely ignored.
We fix this oversight by moving the check to `can_eq_nc_forall`.

JS: use regular mask for blocking IO
Blocking IO used uninterruptibleMask which should make any thread
blocked on IO unreachable by async exceptions (such as those from
timeout). This changes it to a regular mask.
It's important to note that the nodejs runtime does not actually
interrupt the blocking IO when the Haskell thread receives an
async exception, and that file positions may be updated and buffers
may be written after the Haskell thread has already resumed.
Any file descriptor affected by an async exception interruption
should therefore be used with caution.

JS: nodejs: do not set 'readable' handler on stdin at startup
The Haskell runtime used to install a 'readable' handler on stdin
at startup in nodejs. This would cause the nodejs system to start
buffering the stream, causing data loss if the stdin file
descriptor is passed to another process.
This change delays installation of the 'readable' handler until
the first read of stdin by Haskell code.

Report scoped kind variables at the type-checking phase (#16635)
This patch modifies the renamer to respect ScopedTypeVariables in kind
signatures. This means that kind variables bound by the outermost
`forall` now scope over the type:
type F = '[Right @a @() () :: forall a. Either a ()]
-- ^^^^^^^^^^^^^^^ ^^^
-- in scope here bound here
However, any use of such variables is a type error, because we don't
have type-level lambdas to bind them in Core. This is described in the
new Note [Type variable scoping errors during type check] in GHC.Tc.Types.
