Enabling this extension may break some code and the warning

GHC Proposals #448 "Modern scoped type variables"
and #425 "Invisible binders in type declarations"
introduce a new language extension flag: TypeAbstractions.
Part of the functionality guarded by this flag has already been
implemented, namely type abstractions in constructor patterns, but it
was guarded by a combination of TypeApplications and ScopedTypeVariables
instead of a dedicated language extension flag.
This patch does the following:
* introduces a new language extension flag TypeAbstractions
* requires TypeAbstractions for @a-syntax in constructor patterns
instead of TypeApplications and ScopedTypeVariables
* creates a User's Guide page for TypeAbstractions and
moves the "Type Applications in Patterns" section there
To avoid a breaking change, the new flag is implied by
ScopedTypeVariables and is retroactively added to GHC2021.
