e62b144afe lottie: integrate JerryScript engine for expressions
introduced the JerryScript engine to interpret Lottie
expressions, enhancing the capability to support runtime
programmable animation logic within Lottie expressions
spec. This feature, based on js scripting, represents
the most complicated addition to the Lottie spec so far.

ThorVG probably could includes an option to toggle
this feature at build time, allowing for customizable user
configurations according to specific requirements.

removed unused features for the optimal size:
- DEBUGGER
- MEM_STATS
- SNAPSHOT
- BUILTIN_JSON
- BUILTIN_PROXY
- BUILTIN_REFLECT
- BUILTIN_ATOMICS
- PROMISE_CALLBACK
- MODULE_SYSTEM
- SYSTEM_PORT

This is an experimental version.
Please manually enable the 'lottie-expressions' in meson.build
when you wish to use it.

@APIs:
- Result LottieAnimation::override(const char* slotJson) noexcept;
- static std::unique_ptr<LottieAnimation> LottieAnimation::gen() noexcept;
