LibGfx/TinyVG: Fix decoding green channel of graphics RGB565 colors
...
The division was missed here, so this would produce overly bright greens
(or overflow).

LibGfx: Remove suspicious const& in TinyVGLoader
...
`decode_color_table()` returns a vector by value (not reference), so
assigning it to a const reference (while legal), seems odd.

LibGfx/TinyVG: Avoid OOM if header contains a bogus color table size
...
This change limits the amount of memory that is initially allocated for
the color table. This prevents an OOM condition if the file contains an
incorrect color table size.

LibGfx/TinyVG: Parse and ignore line_width in paths
...
TinyVG allows varying the line width along a path, this is not supported
in LibGfx so we just ignore this (but still need to parse the field).

LibGfx: Lazily load TinyVG image data
...
This matches the behavior of other decoders, and ensures just getting
the size (e.g. for the `file` command) does not read the whole file.

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.

LibGfx: Implement image decoder for TinyVG (.tvg)
...
This adds a decoder for the TinyVG vector format (https://tinyvg.tech/ ).
TinyVG is a very simple binary vector format, but it is good enough to
represent a lot of SVGs, without needing the full web engine.
The main use case for Serenity is for scalable icons (which .tvg easily
handles).
