d0403ec14f AK+Everywhere: Rename Utf16View::to_utf8 to to_deprecated_string
A subsequent commit will add to_utf8 back to create an AK::String.

d793262beb AK+Everywhere: Make UTF-16 to UTF-8 converter fallible
This could fail to allocate the underlying storage needed to store the
UTF-8 data. Propagate this error.

1edb96376b AK+Everywhere: Make UTF-8 and UTF-32 to UTF-16 converters fallible
These could fail to allocate the underlying storage needed to store the
UTF-16 data. Propagate these errors.

425c168ded AK+LibJS+LibRegex: Define an alias for UTF-16 string data storage
Instead of writing out "Vector<u16, 1>" everywhere, let's have a name
for it.

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 :^)

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.

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.

9b83cd1abf AK: Add Utf16View for decoding UTF-16 strings
Also includes a way to transcode from and to UTF-8 strings.
