Max Wipfli c1b452f754 AK: Add substring methods to Utf8View ...

This patch implements a Unicode-safe substring method, which can be used
when offset and length should be specified in actual characters instead
of bytes.

This can be used to mitigate issues where a string is split in the
middle of a UTF-8 multi-byte character, which leads to invalid UTF-8.

Furthermore, it implements to common shorthands for substring methods
which take only an offset and return the substring until the end of the
string.
