8064c9fc4d AK: Add unit tests for StringUtils::find_last
This method was added without tests. Add some now to ensure future
changes do not break it.

7578620f25 AK/StringUtils: Ensure needle positions don't overlap in replace
Previously, `replace` used `find_all` to find all of the positions to
replace. But `find_all` finds all the *overlapping* instances of the
needle, while `replace` assumed that the next position was always at
least `needle.length()` away from the last one. This led to crashes like
https://github.com/SerenityOS/jakt/issues/1159.

5e1499d104 Everywhere: Rename {Deprecated => Byte}String
This commit un-deprecates DeprecatedString, and repurposes it as a byte
string.
As the null state has already been removed, there are no other
particularly hairy blockers in repurposing this type as a byte string
(what it _really_ is).

54e1470467 AK: Pass correct length to StringUtils::convert_to_floating_point()
Fixed the issue in StringUtils::convert_to_floating_point() where the
end pointer of the trimmed string was not being passed, causing the
function to consistently return 'None' when given strings with trailing
whitespaces.

f31bd190b0 AK: Ensure string types are actually considered hash-compatible
The AnyString concept is currently broken because it checks whether a
StringView is constructible from a type T. The StringView constructors,
however, only accept constant rvalue references - i.e. `T const&`.

This also adds a test to ensure this continues to work.

af2ffcaba8 AK: Make StringUtils::matches() handle escaping correctly
Previously any backslash and the character following it were ignored.
This commit adds a fall through to match the character following the
backslash without checking whether it is "special".

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 :^)

b9dc0b7d1b AK: Do not append string bytes as code points when title-casing a string
By appending individual bytes as code points, we were "breaking apart"
multi-byte UTF-8 code points. This now behaves the same way as the
invert_case() helper in StringUtils.

a0d44026fc AK+Tests: Correct off-by-one error when right-trimming text
If the entire string you want to right-trim consists of characters you
want to remove, we previously would incorrectly leave the first
character there.

For example: `trim("aaaaa", "a")` would return "a" instead of "".

We can't use `i >= 0` in the loop since that would fail to detect
underflow, so instead we keep `i` in the range `size .. 1` and then
subtract 1 from it when reading the character.

Added some trim() tests while I was at it. (And to confirm that this was
the issue.)

3f3f45580a Everywhere: Add sv suffix to strings relying on StringView(char const*)
Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).

No functional changes.

7e98c8eaf6 AK+Tests: Fix StringUtils::contains() being confused by repeating text
Previously, case-insensitively searching the haystack "Go Go Back" for
the needle "Go Back" would return false:

1. Match the first three characters. "Go ".
2. Notice that 'G' and 'B' don't match.
3. Skip ahead 3 characters, plus 1 for the outer for-loop.
4. Now, the haystack is effectively "o Back", so the match fails.

Reducing the skip by 1 fixes this issue. I'm not 100% convinced this
fixes all cases, but I haven't been able to find any cases where it
doesn't work now. :^)
