Considering that the parser used to create a Bag of binds using a
cons-based approach, it can be also done using lists. The operations in
the compiler don't really require Bag.
By using lists, there is no dependency on GHC.Data.Bag anymore from the
AST.
Progress towards #21592

Progress towards #21592
Specificity, ForAllTyFlag and its' helper functions are extracted from
GHC.Types.Var and moved into a new module Language.Haskell.Syntax.Specificity.
Note: Eventually (i.e. after Language.Haskell.Syntax.Decls does not depend on
GHC.* anymore) these should be moved into Language.Haskell.Syntax.Decls.
At this point, this would cause cyclic dependencies.

Progress towards #21592
This splits HsSrcBang up, creating the new HsBang within
`Language.Haskell.Syntax.Basic`. `HsBang` holds the unpackedness
and strictness information, while `HsSrcBang` only adds the SourceText
for usage within the compiler directly.
Inside the AST, to preserve the SourceText, it is hidden behind the
pre-existing extension point `XBindTy`. All other occurrences of
`HsSrcBang` were adapted to deconstruct the inner `HsBang`, and when
interacting with the `BindTy` constructor, the hidden `SourceText` is
extracted/inserted into the `XBindTy` extension point.
`GHC.Core.DataCon` exports both `HsSrcBang` and `HsBang` for
convenience. A constructor function `mkHsSrcBang` that takes all
individual components has been added.
Two exceptions has been made though:
- The `Outputable HsSrcBang` instance is replaced by
`Outputable HsBang`. While being only GHC-internal, the only place
it's used is in outputting `HsBangTy` constructors -- which already
have `HsBang`. It wouldn't make sense to reconstruct a `HsSrcBang` just
to ignore the `SourceText` anyway.
- The error `TcRnUnexpectedAnnotation` did not use the `SourceText`,
so it too now only holds a `HsBang`.
