thorvg/test/capi/capiLinearGradient.cpp
Hermet Park 4345d6b8a5 API: revise the APIs. 
deprecate the `identifier()` APIs by replacing them with `type()`.

ThorVG is going to introduce an instance `id()`,
and this could be confused with the `identifier()` methods.

with this new type() method can reduce the memory size
by removing unncessary type data.

New Experimental C APIs:
- enum Tvg_Type
- Tvg_Result tvg_paint_get_type(const Tvg_Paint* paint, Tvg_Type* type)
- Tvg_Result tvg_gradient_get_type(const Tvg_Gradient* grad, Tvg_Type* type)

New Experimental C++ APIs:
- Type Paint::type() const
- Type Fill::type() const
- Type LinearGradient::type() const
- Type RadialGradient::type() const
- Type Shape::type() const
- Type Scene::type() const
- Type Picture::type() const
- Type Text::type() const

Deprecated C APIs:
- enum Tvg_Identifier
- Tvg_Result tvg_paint_get_identifier(const Tvg_Paint* paint, Tvg_Identifier* identifier)
- Tvg_Result tvg_gradient_get_identifier(const Tvg_Gradient* grad, Tvg_Identifier* identifier)

Deprecated C++ APIs:
- enum class Type
- uint32_t Paint::identifier() const
- uint32_t Fill::identifier() const
- static uint32_t Picture::identifier()
- static uint32_t Scene::identifier()
- static uint32_t Shape::identifier()
- static uint32_t LinearGradient:identifier()
- static uint32_T RadialGradient::identfier()

Removed Experimental APIs:
- static uint32_t Text::identifier()
