PDO MySQL driver returns integers and floats

Integers and floats in result sets will now be returned using native PHP types instead of strings when using emulated prepared statements.

This effects test artifacts with string API responses like testSegmentEditing-assert-seg3.json property metaCache:
fakeSegId_3\":{\"nr\":\"3\" will become fakeSegId_3\":{\"nr\":3

Potentially many more parts can be affected, so this has to be checked carefully.
Especially places where === is used to compare against a DB response.

Classes implementing PHP built-in interfaces must specify return type

Most of the PHP internal classes are updated with tentative (=preliminary) return types [which ...] will be enforced since PHP 9.0.

PHP 8.1 and later emits a deprecation notice if a class declaration has an incompatible return type and lack of a return type declaration is also considered a return type mismatch.

This affects mainly zf1-future. In this PR the needed return types are added.

Passing null to non-nullable internal function parameters is deprecated

• preg_match(... string $subject)
• file_get_contents( ... bool $use_include_path)
• String functions: trim, str_replace, substr, ...
