This patch normalizes the casing of hexadecimal digits in escape
sequences of the form `\xNN` and integer literals of the form
`0xNNNN`.

Previously, the V8 code base used an inconsistent mixture of uppercase
and lowercase.

Google’s C++ style guide uses uppercase in its examples:
https://google.github.io/styleguide/cppguide.html#Non-ASCII_Characters

Moreover, uppercase letters more clearly stand out from the lowercase
`x` (or `u`) characters at the start, as well as lowercase letters
elsewhere in strings.

Add a third parameter to {AsHex} which specifies whether the prefix
"0x" should be printed. Also, add the {AsHexBytes} helper which
outputs the hex number as individual bytes separated by a whitespace.
Also add unit tests for both helpers.

Both helper will be used in an upcoming refactoring of wasm error
messages:

Previously, we would output \x5c to escape a backslash, but this is
invalid JSON and it would crash Turbolizer. Use \u005c instead.

We divide character ranges into
- BMP, matched normally.
- non-BMP, matched as alternatives of surrogate pair ranges.
- lone surrogates, matched with lookaround assertion that its indeed lone.

VS 2015 supplies a conforming snprintf implementation, so #define
snprintf is no longer needed. Also, VS 2015 checks for #define of
snprintf and treats it as a fatal error.

Use simple HAS-A relationship instead of obscure multiple inheritance.
In theory, UBSan should be totally happy with this, but it still isn't.
This seems to be a bug in UBSan, see e.g.

This is a mostly mechanical CL (more than 90% Emacs macros and
query-replace-regexp) moving FILE*/StringStream*-based APIs to
OStream-based APIs. There are a few places where this had to stop,
otherwise the CL would be even bigger, but this can easily and
incrementally cleaned up later.

Our clang/win build currently uses MSVS's C library, so it doesn't have
snprintf but it does have sprintf_s.
