Hermet Park e7a94f5314 common Animation: introduce the Animation class.
This class serves as the base for Animation.
The main purpose of its APIs is to control the animation frames.

Its example will be provided in the upcoming commits.

@APIs:
Result Animation::frame(uint32_t no) noexcept;
Picture* Animation::picture() const noexcept;
uint32_t Animation::curFrame() const noexcept;
uint32_t Animation::totalFrame() const noexcept;
float Animation::duration() const noexcept;
static std::unique_ptr<Animation> Animation::gen() noexcept;
