dc65f54c06 AK: Rename Vector::append(Vector) => Vector::extend(Vector)
Let's make it a bit more clear when we're appending the elements from
one vector to the end of another vector.

a49c77b76d LibGfx: Load correct durations for gifs
The wrong shift effectively set the upper byte to 0, meaning that
durations longer than 255 centiseconds (2.55 seconds) were wrapped
around. See serenity-fuzz-corpora for an example.

5e1c1eb840 LibGfx: Make sure we use unique class names
Previously there were different definitions for classes with the
same name. This is a violation of the C++ ODR.

480802805f LibGfx: Copy into a u32 in LZWDecoder::next_code() instead of casting
This results in unaligned reads sometimes, depending on the layout of
the underlying buffer. Caught by UBSAN.

d60ebbbba6 Revert "Userland: static vs non-static constexpr variables"
This reverts commit 800ea8ea96.

Booting the system no longer worked after these changes.

800ea8ea96 Userland: static vs non-static constexpr variables
Problem:
- `static` variables consume memory and sometimes are less
  optimizable.
- `static const` variables can be `constexpr`, usually.
- `static` function-local variables require an initialization check
  every time the function is run.

Solution:
- If a global `static` variable is only used in a single function then
  move it into the function and make it non-`static` and `constexpr`.
- Make all global `static` variables `constexpr` instead of `const`.
- Change function-local `static const[expr]` variables to be just
  `constexpr`.

1682f0b760 Everything: Move to SPDX license identifiers in all files.
SPDX License Identifiers are a more compact / standardized
way of representing file license information.

See: https://spdx.dev/resources/use/#identifiers

This was done with the `ambr` search and replace tool.

e873d27ab1 LibGfx: Switch a bunch of API's from taking StringView to String
These were all getting converted into String internally anyway.

e0f32626bc LibGfx: Rename 32-bit BitmapFormats to BGRA8888 and BGRx888x
The previous names (RGBA32 and RGB32) were misleading since that's not
the actual byte order in memory. The new names reflect exactly how the
color values get laid out in bitmap data.

ce5fe2a6e8 LibGfx: Fix read buffer overflow in interlaced GIF decode
Unfortunately 10420dee7e didn't quite fix it,
as the buffer overflow was actually happening here:
af22204488/Userland/Libraries/LibGfx/GIFLoader.cpp (L402)

Found by oss-fuzz: https://bugs.chromium.org/p/oss-fuzz/issues/detail?id=30507

5d180d1f99 Everywhere: Rename ASSERT => VERIFY
(...and ASSERT_NOT_REACHED => VERIFY_NOT_REACHED)

Since all of these checks are done in release builds as well,
let's rename them to VERIFY to prevent confusion, as everyone is
used to assertions being compiled out in release.

We can introduce a new ASSERT macro that is specifically for debug
checks, but I'm doing this wholesale conversion first since we've
accumulated thousands of these already, and it's not immediately
obvious which ones are suitable for ASSERT.

57e10eadac LibGfx: Don't reject valid GIF animations with interlaced frames
We were returning early from the deinterlacing loop after the very last
pass, but we should just let the outer loop finish and return instead.

This makes the Netscape animation on https://timmorgan.dev work. :^)

449d56ef74 LibGfx: Don't use Gfx::Painter in GIF decoder
Painter currently tries to load fonts, which won't work if we're in a
tightly pledged process.

It was only used to fill a rect with transparent pixels, so just do
that manually instead.

8465683dcf Everywhere: Debug macros instead of constexpr.
This was done with the following script:

    find . \( -name '*.cpp' -o -name '*.h' -o -name '*.in' \) -not -path './Toolchain/*' -not -path './Build/*' -exec sed -i -E 's/dbgln<debug_([a-z_]+)>/dbgln<\U\1_DEBUG>/' {} \;

    find . \( -name '*.cpp' -o -name '*.h' -o -name '*.in' \) -not -path './Toolchain/*' -not -path './Build/*' -exec sed -i -E 's/if constexpr \(debug_([a-z0-9_]+)/if constexpr \(\U\1_DEBUG/' {} \;

1a3a0836c0 Everywhere: Use CMake to generate AK/Debug.h.
This was done with the help of several scripts, I dump them here to
easily find them later:

    awk '/#ifdef/ { print "#cmakedefine01 "$2 }' AK/Debug.h.in

    for debug_macro in $(awk '/#ifdef/ { print $2 }' AK/Debug.h.in)
    do
        find . \( -name '*.cpp' -o -name '*.h' -o -name '*.in' \) -not -path './Toolchain/*' -not -path './Build/*' -exec sed -i -E 's/#ifdef '$debug_macro'/#if '$debug_macro'/' {} \;
    done

    # Remember to remove WRAPPER_GERNERATOR_DEBUG from the list.
    awk '/#cmake/ { print "set("$2" ON)" }' AK/Debug.h.in

These changes are arbitrarily divided into multiple commits to make it
easier to find potentially introduced bugs with git bisect.
