removed unused static condition.
static was prepared for optimization,
but not used at all.
we will revisit this later when time permits.

When lottie is broken and provides invalid gradient, the program crashes in segmentation fault.
At that time, in the `populate` function, `ColorStop& color` doesn't have `input` but tries to use it.
Added checking nullptr logic. The function `populate` will not proceed and return 0 in that case.

Slot overriding tries to set property via the `LottieObject`. It potentially causes unexpected changes.
Revised the `override` function. The purpose of this patch is to aim atomic property to be overriden.
Implemented the ability to revert Lottie slots by calling override with nullptr.
This functionality allows for the complete reversal of applied slots.
usage:
- `animation->override(nullptr)`

When image data fails to load or image parsing fails,
the id is leaked without being assigned to the name.
To prevent that, free id value when obj is nullptr.

When json file is invalid in the parser,
the LottieComposition object is not released and the parse() returns false.
To prevent memory leaks, free the memory before returning false.

Enhances the portability of the TTF loader on UWP platforms
by implementing an alternative file loading mechanism.
This is designed to support environments where the file mapping
feature is not available, ensuring wider compatibility and reliability
in file handling.

error: storing the address of local variable 'context' in '*this.LottieParser::context' [-Werror=dangling-pointer=]

The lottie format defines the starting point for
drawing rectangles and ellipses differently than
the API available in the TVG. In the case of using
dashes or trim paths, this leads to discrepancies.
Therefore, when using the lottie builder, internal
functions for appending rectangles and circles are
utilized.

This class extends the Animation and serves advanced Lottie features.
It's designed to separately have Lottie Animation's unique specs.
For now, this will have Slot overriding feature,
you can include <thorvg_lottie.h> for its extensive features.
@APIs:
- Result LottieAnimation::override(const char* slotJson) noexcept;
- static std::unique_ptr<LottieAnimation> LottieAnimation::gen() noexcept;
@Issue: https://github.com/thorvg/thorvg/issues/1808
Internal model and parser modifications have been made
to parse "sid" and retrieve their data into the LottieComposition.
This will enable dynamic changes to the following Lottie objects:
The slot feature will encompass these properties:
- LottieSolidStroke
- LottieSolidFill
- LottieGradientStroke
- LottieGradientFill
- LottieTextDoc"

To ensure consistent properties, `LottieSolid` has been defined.
Both `LottieSolidStroke` and `LottieSolidFill` can be typecasted to the `LottieSolid`.
Improve parenthesis checking and space checking.
- There must be only one pair of parentheses.
- There cannot be spaces(and ') between id strings.

Dashed curves require greater precision in calculating
their lengths and while splitting Bezier curves.
Otherwise, it results in visual discrepancies compared
to the expected outcomes.
Approximate functions 'bezLengthApprox' and 'bezAtApprox'
used for calculations in the lottie loader.

enhance decoding efficiency by determining the desired canvas format
during image loading. This allows loaders to preemptively decode
the image in the specified format, to not convert the format again.
