Remove ParserFactory::create()

Don't try to keep backwards-compatibility with the old factory
style, which doesn't map cleanly onto supported options (we only
have ONLY_PHP7/PREFER_PHP7, which should probably create a Php8
parser in terms of how they are used, but this would no longer
match their names).

Instead, I have backported the new createForNewestSupportedVersion()
and createForHostVersion() methods to PHP-Parser 4.

Don't align phpdoc tags

I did this to start with, but then alignment kept being broken
during refactorings, and at some point I switched to not aligning,
and now we have a big mess.

Don't align phpdoc tags

Add a php-cs-fixer rule to consistently not align phpdoc tags.

Move attribute handling into parser

The Lexer now only provides the tokens to the parser, while the
parser is responsible for determining which attributes are placed
on notes. This only needs to be done when the attributes are
actually needed, rather than for all tokens.

This removes the usedAttributes lexer option (and lexer options
entirely). The attributes are now enabled unconditionally. They
have less overhead now, and the need to explicitly enable them for
some use cases (e.g. formatting-preserving printing) doesn't seem
like a good tradeoff anymore.

There are some additional changes to the Lexer interface that
should be done after this, and the docs / upgrading guide haven't
been adjusted yet.

Improve ParserFactory version targeting

Most users will want to pick createForNewestSupportedVersion()
or getForHostVersion(). The currently default is the former,
which can lead to unwanted surprised due to PHP BC breaks for
users that actually want the latter. Make this choice more
explicit.
