Summary:

Phase 4 of moving MultiTypeExperiment features into base Experiment.

Updates the base Experiment's _fetch_trial_data to filter metrics by trial type when _trial_type_to_metric_names is populated. Only metrics whose names appear in the set for the trial's type are fetched, preventing metrics from being evaluated against trials of the wrong type.

Updates fetch_data to iterate trial-by-trial when _trial_type_to_metric_names is populated (so each trial fetches only its relevant metrics), while preserving the existing bulk fetch path for single-type experiments.

Removes the fetch_data and _fetch_trial_data overrides from MultiTypeExperiment, along with now-unused imports (Iterable, Data, MetricFetchResult).

Summary:
This is Phase 1 of moving MultiTypeExperiment features into the base
Experiment class, enabling eventual deprecation of MultiTypeExperiment.

Adds `_trial_type_to_metric_names: dict[str, set[str]]` to Experiment —
a mapping from trial type to the set of metric names relevant to that
type. This is the natural complement to the existing
`_trial_type_to_runner` dict. Along with it, adds the following
properties and methods to Experiment:

- `trial_type_to_metric_names`: read-only property (shallow copy)
- `metric_to_trial_type`: computed inverse mapping, with optimization
  config metrics pinned to `default_trial_type`
- `metrics_for_trial_type(trial_type)`: returns Metric objects for a
  given trial type
- `default_trials`: returns trial indices matching the default type

MultiTypeExperiment is updated to populate `_trial_type_to_metric_names`
alongside `_metric_to_trial_type` in all mutation paths (init,
optimization_config setter, add/update/remove tracking metric). The
redundant MTE overrides for `metric_to_trial_type`,
`metrics_for_trial_type`, `default_trials`, and `default_trial_type`
are removed — they are now inherited from the base class.

The JSON decoder is updated to rebuild `_trial_type_to_metric_names`
from `_metric_to_trial_type` during deserialization for backward
compatibility.

Summary:
Phase 2 of moving MultiTypeExperiment features into base Experiment.

Updates the base Experiment metric management methods (`add_metric`, `update_metric`, `remove_metric`) to accept an optional `trial_type` parameter. When provided, metrics are associated with the specified trial type in `_trial_type_to_metric_names`. The `__init__` and `optimization_config` setter also now register metrics when `default_trial_type` is set.

The deprecated wrappers (`add_tracking_metric`, `add_tracking_metrics`, `update_tracking_metric`) now accept and pass through `trial_type` and `canonical_name` parameters.

On MultiTypeExperiment, overrides are simplified to delegate to the base class methods:
- `add_tracking_metric` delegates to `self.add_metric()`
- `add_tracking_metrics` override removed (inherited from base)
- `update_tracking_metric` delegates to `self.update_metric()`
- `remove_tracking_metric` replaced with `remove_metric` override

Summary:
Phase 3 of moving MultiTypeExperiment features into base Experiment.

Moves `add_trial_type` and `update_runner` from MultiTypeExperiment to the base Experiment class, making them available to all experiments.

Updates `supports_trial_type` to unify the logic: for multi-type experiments (where `default_trial_type` is set), only trial types registered in `_trial_type_to_runner` are supported. For single-type experiments, `None` is supported along with `SHORT_RUN` and `LONG_RUN` for backward compatibility with generation strategies that use those trial types.

Removes the corresponding overrides from MultiTypeExperiment — all three methods are now inherited from the base class.
