Fix lineno in backtrace of multi-line function calls

[iluuu1994]

Closes GH-8810

@derickr Do you see any issues with this for Xdebug?

Actually, this should also handle the following:

(new A())
    ->b()
    ->c();

so we'll need some more tweaks.

The line number should now always be the lineno of the function/method name:

foo // <- This line
(
)

$foo
    ->
    bar  // <- This line
    (
    )

Foo
    ::
    bar  // <- This line
    (
    )

new
    Foo  // <- This line
    (
    )

The only exception is when the LHS is dynamic:

(function () {

})
( // <- This line
    'foo',
)

'foo'
    ( // <- This line
        'bar',
    )
