a1f9d2420f Fuzzers: Disable debug logging for all fuzzers
Previously, some fuzzers were generating an excessive amount of debug
logging. This change explicitly disables debug logging for all fuzzers.
This allows higher test throughput and makes the logs easier to read
when fuzzing locally.

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

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:

57e19a7e56 LibGfx: Re-structure the whole initialization pattern for image decoders
When trying to figure out the correct implementation, we now have a very
strong distinction on plugins that are well suited for sniffing, and
plugins that need a MIME type to be chosen.

Instead of having multiple calls to non-static virtual sniff methods for
each Image decoding plugin, we have 2 static methods for each
implementation:
1. The sniff method, which in contrast to the old method, gets a
    ReadonlyBytes parameter and ensures we can figure out the result
    with zero heap allocations for most implementations.
2. The create method, which just creates a new instance so we don't
    expose the constructor to everyone anymore.

In addition to that, we have a new virtual method called initialize,
which has a per-implementation initialization pattern to actually ensure
each implementation can construct a decoder object, and then have a
correct context being applied to it for the actual decoding.

6e19ab2bbc AK+Everywhere: Rename String to DeprecatedString
We have a new, improved string type coming up in AK (OOM aware, no null
state), and while it's going to use UTF-8, the name UTF8String is a
mouthful - so let's free up the String name by renaming the existing
class.
Making the old one have an annoying name will hopefully also help with
quick adoption :^)

This is a first step towards better error propagation from image codecs.

2b866e3c9b LibGfx: Remove ImageDecoderPlugin::bitmap() in favor of frame(index)
To encourage proper support for multi-frame images throughout the
system, get rid of the single-frame convenience bitmap() API.
