ext/exif: Replace zend_parse_parameters() with ZEND_PARSE_PARAMETERS macros

[arshidkv12]

This replaces zend_parse_parameters() with the ZEND_PARSE_PARAMETERS_START/END macros, which provide
exception-aware parameter parsing and align the code with modern php-src conventions.

If this is done, it should be consistently done for exif_imagetype() as well.

This replaces zend_parse_parameters() with the ZEND_PARSE_PARAMETERS_START/END macros, which provide exception-aware parameter parsing and align the code with modern php-src conventions.

zend_parse_parameters() is also exception aware. And it is not really a modern convention, Fast ZPP got introduced to reduce the overhead of calling ZPP for hot/short functions. Fast ZPP introduces some code bloat into every function, although @ndossche knows more the details about this.

So I'm not sure whether that's really a good motivation here.

I think fast ZPP is indirectly more secure, because null-safety is part of it.
