6bb7e5c086 Handle parentless nodes in isParameterPropertyDeclaration 
Fixes #33295.

This follows a similar pattern as in #20314 by requiring an explicit
`parent` parameter. Where possible, it uses the appopriate variable at
the call sites.

In several locations there is no context available though (e.g.
inspecting `valueDeclarations`) and we access `.parent` as the code
previously did. From a cursory inspection this seems correct, these
callpaths originate in phases where there must be a `parent` (i.e. in
checker, binder, etc).
