Remove some AMQP stubs for functionMap

[VincentLanglet]

Same idea than #4185
I checked the signature one by one.

More could be removed when PHPStorm will be fixed
JetBrains/phpstorm-stubs#1775

The only change in reflection golden tests is

PHPStan\Reflection\ReflectionProviderGoldenTest::test with data set "METHOD AMQPExchange::delete" ('METHOD AMQPExchange::delete', 'Is built-in: Yes\nHas side-ef... mixed')
Failed asserting that two strings are identical.

Which seems legit when looking at
https://github.com/php-amqp/php-amqp/blob/3618db5f781aa3d371b630c666bc90845d7c77d4/stubs/AMQPExchange.php#L114
