-Wterm-variable-capture wasn't accordant with type variable
scoping in associated types, in type classes. For example,
this code produced the warning:
k = 12
class C k a where
type AT a :: k -> Type
I solved this issue by reusing machinery of newTyVarNameRn function
that is accordand with associated types: it does lookup for each free type
variable when we are in the type class context. And in this patch I
use result of this work to make sure that -Wterm-variable-capture warns
only on implicitly quantified type variables.

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 cache
the "effective" (small) diagnosticReason, which is then used for
pretty-printing of the diagnostic.

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).
