feat: add navigation flavor to demo for SDK 7.x reproduction (#1680)

* feat: add navigation flavor to demo for SDK 7.x reproduction

* docs: header

* fix: enable core library desugaring for navigation flavor

* fix: move GMS version meta-data to standard flavor manifest

* docs: header

* fix: remove GMS version from library manifest to support exclusion

* fix: update CI SARIF paths after adding flavors

* fix: explicit lint tasks and default flavor to resolve CI paths

* fix: use consistent lint-results.sarif paths in CI

* fix: update navigation SDK and use version catalog for desugaring

* fix: update desugar-jdk-libs to 2.1.5
