Fix 'php-ts-mode': better indentation and font locking

Fix 'php-ts-mode': better indentation and font locking

Incomplete compound_statement or colon_block (statement-group
without a closing brace or closing keyword) that are not inside
a function or method are not recognized as such by tree-sitter-php.
A new function 'php-ts-mode--open-statement-group-heuristic'
handles this case.  Font locking of magic methods and better
support for alternative control structure syntax.
Support for latest grammar version.
