ae3ffdd521 AK: Make it possible to not using AK classes into the global namespace
This patch adds the `USING_AK_GLOBALLY` macro which is enabled by
default, but can be overridden by build flags.

This is a step towards integrating Jakt and AK types.

4296425bd8 Everywhere: Remove redundant inequality comparison operators
C++20 can automatically synthesize `operator!=` from `operator==`, so
there is no point in writing such functions by hand if all they do is
call through to `operator==`.

This fixes a compile error with compilers that implement P2468 (Clang
16 currently). This paper restores the C++17 behavior that if both
`T::operator==(U)` and `T::operator!=(U)` exist, `U == T` won't be
rewritten in reverse to call `T::operator==(U)`. Removing `!=` operators
makes the rewriting possible again.

44e8c05c67 AK: Add a Utf16View::code_unit_offset_of(Utf16CodePointIterator) helper
This helper can be used to used to retrieve the code unit offset of an
active Utf16CodePointIterator efficiently.

216e21a1fa AK: Convert AK::Format formatting helpers to returning ErrorOr<void>
This isn't a complete conversion to ErrorOr<void>, but a good chunk.
The end goal here is to propagate buffer allocation failures to the
caller, and allow the use of TRY() with formatting functions.

024367d82e LibJS+AK: Use Vector<u16, 1> for UTF-16 string storage
It's very common to encounter single-character strings in JavaScript on
the web. We can make such strings significantly lighter by having a
1-character inline capacity on the Vectors.

70080feab2 AK+LibJS: Implement String.from{CharCode,CodePoint} using UTF-16 strings
Most of String.prototype and RegExp.prototype is implemented with UTF-16
so this is to prevent extra copying of the string data.

510bbcd8e0 AK+LibRegex: Add Utf16View::code_point_at and use it in RegexStringView
The current method of iterating through the string to access a code
point hurts performance quite badly for very large strings. The test262
test "RegExp/property-escapes/generated/Any.js" previously took 3 hours
to complete; this one change brings it down to under 10 seconds.

0e6375558d AK+LibRegex: Partially implement case insensitive UTF-16 comparison
This will work for ASCII code points. Unicode case folding will be
needed for non-ASCII.

2e45e52993 AK: Add UTF-16 helper methods required for use within LibRegex
To be used as a RegexStringView variant, Utf16View must provide a couple
more helper methods. It must also not default its assignment operators,
because that implicitly deletes move/copy constructors.

Also includes a way to transcode from and to UTF-8 strings.
