Happy new year!

##### Enhancements

- \[FIR] Add diagnostic for multiple graph-like annotations on a single
declaration.
- \[IR] Stub `@Binds` expressions in origin points rather than graphs.
This reduces unnecessary extra generated functions.
- \[IR] Generate reusable getters for scalar-only dependencies that are
used multiple times. This helps avoid `MethodTooLargeException` errors
in the JVM.
- \[IR] Detect suspicious member injections from inherited inject
functions too.
- \[IR] Don't try to validate graphs if `QualifierOverrideMismatch`
errors were reported prior to graph validation. This helps reduce noise
in failure cases, as it would otherwise also likely report
`MissingBinding` errors caused by the source of the
`QualifierOverrideMismatch` error.

##### Fixes

- \[FIR, Anvil Interop] Fix rank-based binding replacements getting
dropped for multi-contribution classes in root graphs when contributions
are from external modules.
- \[FIR] Named annotation arguments in different order from declared
parameters getting silently skipped.
- \[FIR] Fix `Map<K, Provider<V>>` parameters to `@Provides` functions
mistakenly unwrapping the Provider value type.
- \[FIR] Disallow star projections in `@ElementsIntoSet` binding types.
- \[FIR] Require exactly one generic type argument `@ElementsIntoSet`
binding types.
- \[IR, Anvil Interop] Fix rank-based binding replacements getting
dropped for multi-contribution classes in graph extensions when
contributions are from external modules.
-   \[IR] Prohibit duplicate map keys.
- \[IR] Fix propagation of scoped multibinding sources to graph
extensions.
- \[IR] Don't eagerly validate duplicate bindings (only report them if
used).
- \[IC] Fix member injection metadata not always being written and
causing IC issues with member inject function transformation.
- \[Gradle] Report all tested Kotlin versions when emitting
compatibility warnings.

##### Changes

- \[FIR] Change `SUSPICIOUS_MEMBER_INJECT_FUNCTION` diagnostic to be a
warning instead of an error.
- Remove testing of 2.3.0 pre-releases. IntelliJ stable currently builds
off Kotlin `2.3.2x` and Android Studio stable currently points to Kotlin
`2.2.2x`.
