bbf66ea055 LibGfx: Remove maximum size limit for decoded images 
It is unlikely this is needed anymore, and as pointed out things should
now safely return OOM if the bitmap is too large to allocate.

Also, no recently added decoders respected this limit anyway.

Fixes #20872

806808f406 LibGfx: Provide a default implementation for animation-related methods 
Most image decoders that we have only support non-animated images,
providing a default implementation for them allows to remove quite some
code.

7acb656826 LibGfx: Comment ImageDecoderPlugin's interface 
This is done as an effort to unify the behavior of every plugin. See
#19893 for more details.

4291288a31 LibGfx: Remove ImageDecoderPlugin::initialize() 
No plugin is currently overriding the default implementation, which is a
no-op. So we can safely delete it.

753cf04be8 LibGfx: Allow requesting vector graphic frames from ImageDecoder 
Only supported for plugins that set is_vector() to true. This returns
the frames as Gfx::VectorGraphics, which allows painting/rasterizing
them with arbitrary transforms and scales.

babe924da1 LibGfx: Provide a default implementation for ImageDecoder::initialize 
In order to ease the removal of this function, let's provide a no-op
default implementation so decoders can stop implementing it one by one.

First step of #19893

e7cddda7e1 LibGfx: Allow passing an ideal size to image decoders 
The ideal size is the size the user will display the image. Raster
formats should ignore this parameter, but vector formats can use
it to generate a bitmap of the ideal size.

da394abe04 LibGfx+Fuzz: Convert ImageDecoder::initialize to ErrorOr 
This prevents callers from accidentally discarding the result of
initialize(), which was the root cause of this OSS Fuzz bug:

animations.
