AK+Everywhere: Rename String to DeprecatedString

Browse source 
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 :^)

# String Formatting
Many places in Serenity allow you to format strings, similar to `printf()`, for example `String::formatted()`
Many places in Serenity allow you to format strings, similar to `printf()`, for example `DeprecatedString::formatted()`
, `StringBuilder::appendff()`, or `dbgln()`. These are checked at compile time to ensure the format string matches the
number of parameters. The syntax is largely based on
the [C++ `std::formatter` syntax](https://en.cppreference.com/w/cpp/utility/format/formatter#Standard_format_specification)
@ -10,27 +10,27 @@ For basic usage, any occurrences of `{}` in the format string are replaced with
form, in order:
```c++
String::formatted("Well, {} my {} friends!", "hello", 42) == "Well, hello my 42 friends!";
DeprecatedString::formatted("Well, {} my {} friends!", "hello", 42) == "Well, hello my 42 friends!";
```
If you want to include a literal `{` in the output, use `{{`:
```c++
String::formatted("{{ {}", "hello") == "{ hello";
DeprecatedString::formatted("{{ {}", "hello") == "{ hello";
```
You can refer to the arguments by index, if you want to repeat one or change the order:
```c++
String::formatted("{2}{0}{1}", "a", "b", "c") == "cab";
DeprecatedString::formatted("{2}{0}{1}", "a", "b", "c") == "cab";
```
To control how the arguments are formatted, add colon after the optional index, and then add format specifier
characters:
```c++
String::formatted("{:.4}", "cool dude") == "cool";
String::formatted("{0:.4}", "cool dude") == "cool";
DeprecatedString::formatted("{:.4}", "cool dude") == "cool";
DeprecatedString::formatted("{0:.4}", "cool dude") == "cool";
```
