LibGfx/TGA: Simplify the code by converting it to use AK::Stream
...
The conversion to AK::Stream makes everything much more straightforward

Because AK::Stream is more tested, it means that the code should be now
more robust against bugs as well.

Both width and height are stored in an u16 inside the TGA header,
computing the total number of pixel without using another type can
easily lead to overflows.

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.
