Description

Acquire the feature. If this is the first acquire for Key (0 -> 1), Install will be executed and the provided Install/Uninstall callbacks will be stored as the feature definition for this context.

If the feature is already acquired (RefCount > 0), the stored Install/Uninstall callbacks are retained. Callers may pass callbacks again (eg from immutable ToolGroup descriptors); these callbacks are ignored and only the ref-count is incremented.

Note: Feature keys are expected to uniquely identify feature behavior within a context. If multiple callers provide different implementations for the same key, behavior is defined by the first acquire.
