Adjust tests to be compatible with PHPUnit 10 (#998)

This avoids warnings on PHPUnit 10, without actually
switching to PHPUnit 10.

Add missing void return types (#997)

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.

Represent names using string rather than array of parts

In most circumstances we are interested in the whole string, not
the parts split by namespace separator. As names are common, this
representation measurably improves memory usage and performance.

Rename Scalar\LNumber to Scalar\Int_

Rename Expr\ArrayItem to ArrayItem

Array items are not expressions by themselves.

Format tests as well

The unnecessary parentheses for "new" are a bit annoying, but I
can live with it...
