feat(react-drawer): expose drawer base hooks

[dmytrokirpa]

This pull request introduces a minor feature update to the @fluentui/react-drawer package, focusing on improving extensibility and type safety by exporting new base hooks and types, and refactoring how drawer size is handled. The changes make it easier for consumers to access and use base drawer logic and types, and clarify the separation between base and size-related properties. Additional tests ensure that the new size handling works as expected.

Pull request overview

This PR adds new public “base” hooks/types to @fluentui/react-drawer and refactors drawer sizing into a dedicated DrawerSizeProps type to improve extensibility and type safety.

Changes:

• Export new base APIs (useDrawerBase_unstable, DrawerBase* types, DrawerSize* types, useDrawerHeaderTitleBase_unstable).
• Refactor size handling out of DrawerBaseProps into DrawerSizeProps and update internal typing accordingly.
• Add unit tests validating size/defaulting behavior and state shape.
