[Frontend] Make DiagnosticSuppressor a project-level extension

Originally it was an application-level component, which caused non-trivial
  logic and cognitive load to carefully handle those extensions to avoid
  memory leaks.

6740a596 introduced a way to easily register `DiagnosticSuppressor` to
  project, and this commit continues this work, making it a proper
  project-level extension

A lot of changes caused by the fact, that this extension is needed to be
  obtained from `BindingContext` (see `BindingContextSuppressCache` and
  its usages), so almost all changes are introducing `Project` to
  `BindingContext`
