Juan Linietsky a40fe16866 Implement audio stream playback parameters.
Implements a way for audio stream playback to be configured via parameters
directly in the edited AudioStreamPlayer[2D/3D].

Currently, configuring the playback stream is not possible (or is sometimes hacky
as the user has to obtain the currently played stream, which is not always immediately available).

This PR only implements this new feature to control looping in stream playback instances (a commonly requested feature, which was lost in the transition from Godot 2 to Godot 3).
But the idea is that it can do a lot more:

* If effects are bundled to the stream, control per playback instance parameters such as cutoff or resoance, or any other exposed effect parameter per playback instance.
* For the upcoming interactive music PR (#64488), this exposes an easy way to change the active clip, which was not possible before.
* For the upcoming parametrizable audio support (https://github.com/godotengine/godot-proposals/issues/3394) this allows editing and animating audio graph parameters.

In any case, this PR is required to complete #64488.

Return the controllable parameters of this stream. This array contains dictionaries with a property info description format (see [method Object.get_property_list]). Additionally, the default value for this parameter must be added tho each dictionary in "default_value" field.

<method name="instantiate_playback">
<return type="AudioStreamPlayback" />
<description>
Returns an AudioStreamPlayback. Useful for when you want to extend [method _instantiate_playback] but call [method instantiate_playback] from an internally held AudioStream subresource. An example of this can be found in the source files for [code]AudioStreamRandomPitch::instantiate_playback[/code].

Returns true if this audio stream only supports monophonic playback, or false if the audio stream supports polyphony.
