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)

Drop some @covers annotations

Default pretty printer to PHP 7.4

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.

Allow passing visitors to NodeTraverser constructor

Support CRLF newlines in pretty printer

Can be enabled using the "newlines" option.

Support readonly anonymous classes

Doc strings have a trailing \n and these will get interpreted as

Handle isolated \r in doc string

Doc strings have a trailing \n and these will get interpreted as
\r\n and removed from the string contents.

For nowdoc, fall back to single quote if there's a trailing \r.
For heredoc, escape all isolated \r -- unlike \n and \r\n this is
really a special character, because this is no longer relevant as
an actual newline character.

Perform end label check on escaped string

Escaping might convert a label character into an escape sequence
if it is not valid UTF-8.

Handle interpolated variable after end label

Interpolated variables start with non-label characters, and as
such also count as end label terminators since PHP 7.3.

Update allowed characters after doc string label

With the introduction of flexible doc strings, the ending label
is no longer required to be followed by a semicolon or newline.
We need to prevent doc string printing if the label is followed
by any non-label character.

Print INF as 1.0E+1000

This makes pretty printing round trip to another Float literal,
rather than a constant lookup. The 1e1000 form in particular is
chosen because that seems to be the typical form used in various
tests.

Rename Scalar\Encapsed to Scalar\InterpolatedString

Rename Scalar\EncapsedStringPart to InterpolatedStringPart

It is no longer an expression node, which unfortunately does
require a more awkward type for the Encaps node.

Rename Scalar\LNumber to Scalar\Int_

Rename Scalar\DNumber to Scalar\Float_

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...

Don't force newline after doc string when targeting PHP >= 7.3
