Commit Message

Allow injecting bootstrap info into xDS Filter API for config parsing (#12724)

Extend the xDS Filter API to support injecting bootstrap information
into filters during configuration parsing. This allows filters to access
context information (e.g., allowed gRPC services) from the resource loading
layer during configuration validation and parsing.

- Update `Filter.Provider.parseFilterConfig` and
`parseFilterConfigOverride`
  to accept a `FilterContext` parameter.
- Introduce `BootstrapInfoGrpcServiceContextProvider` to encapsulate
  bootstrap info for context resolution.
- Update `XdsListenerResource` and `XdsRouteConfigureResource` to
  construct and pass `FilterContext` during configuration parsing.
- Update sub-filters (`FaultFilter`, `RbacFilter`,
`GcpAuthenticationFilter`,
  `RouterFilter`) to match the updated `FilterContext` signature.

Known Gaps & Limitations:
1. **MetricHolder**: Propagation of `MetricHolder` is not supported with
   this approach currently and is planned for support in a later phase.
2. **NameResolverRegistry**: Propagation is deferred for consistency.
While it could be passed from `XdsNameResolver` on the client side, there is
no equivalent mechanism on the server side. To ensure consistent
behavior, `DefaultRegistry` is used when validating schemes and creating channels.
