This allows Meson to properly track dependencies and re-build the scanner when
editing the dtd. We also stop depending on GNU as' .incbin and make the
embedding less obscure.

Before this patch:
$ scanelf -lpqe ./wayland-scanner
RWX --- --- ./wayland-scanner
That indicates the stack is executable, which is a bad thing for
security. Wayland-scanner does not actually need an executable stack, it
is just an oversight from using an .S file in the sources.
Add a special incantation in dtddata.S to make it not cause the stack to
become executable.

Stop using .altmacro in dtddata.S, because clang does not yet implement
it. Turns out that we do not actually seem to need it, and we can modify
the syntax to work without it.
Moving the double quotes from the binfile line to the .incbin line is
required to avoid the assembler error "missing string". Instead of & we
now use \() to mark the end of macro argument name.

Embed the wayland.dtd protocol data into the scanner binary so we can validate
external protocol files without requiring makefile changes. Hat-tip to Pekka
Paalanen for the embedding trick.
The embedding trick doesn't work well if the to-be-embedded file is in a
different location than the source file, so copy/link it during configure and
then build it in from the local directory.
The current expat parser is not a validating parser, moving scanner.c to
another parser has the risk of breaking compatibility. This patch adds libxml2
as extra (optional) dependency, but that also requires parsing the input
twice.
If the protocol fails validation a warning is printed but no error is returned
otherwise.
