feat: add support for analyzer 9.0.0 (#1065)

* add support for analyzer 9.0.0

# Conflicts:
#	mobx_codegen/CHANGELOG.md

* fix: use explicit type filtering in LibraryScopedNameFinder

* chore: require analyzer ^9.0.0

Drop support for analyzer versions prior to 9.0.0.
Range-based constraints no longer viable due to breaking
API changes between major versions.

* docs: update changelog for analyzer ^9.0.0 requirement
