Create new header and namespace, `SkUTF` where we are putting all of our
robust, well documented UTF-8, UTF-16, and UTF-32 functions:
`SkUTF::{Count,Next,To}UTF{8,16,32}()`.
SkUTF.h and SkUTF.cpp do not depend on the rest of Skia and are suitable
for re-use in other modules.
Some of the old UTF-{8,16} functions still live in SkUtils.h; their use
will be phased out in future CLs.
Also added more unit testing and cleaned up old tests.
Removed functions that were unused outside of tests or used only once.

We currently blow through string chars without checking for end-of-input.
Maybe we could avoid this upfront, when we locate the stop char: try to
determine if it's part of an unterminated string, fail immediately if
so. Figuring out if the tail is an unterminated string seems
intractable though (requires arbitrarily deep tail parsing).
That brings us to plan B:
* treat scope-closing tokens (} & ]) as string terminators
(we know end-of-input points to one of these for sure)
* adjust matchString() to check for end-of-input

ASAN opines that a nullptr memcpy dest is undefined behavior, even when
n == 0. ASAN may be right.
This doesn't occur internally, in the parser, but can be triggered with
the DOM builder API (as do some tests currently).
We could say "don't do that", but if someone wants to build an empty
string/array/object, it's kind of awkward to force them to provide a
valid source pointer instead of simply e.g. Array(nullptr, 0).
So let's guard for this case to make ASAN happy.
