Remove "inline" and "reified" keywords from jOOQ-kotlin extensions where unnecessary

[lukaseder]

The kotlin extensions module jOOQ-kotlin contains a few inline functions, some of which have reified generics. Both language features are unnecessary, and discouraged in our case by the kotlin compiler via warning:

Expected performance impact from inlining is insignificant. Inlining works best for functions with parameters of functional types

The runtime overhead of removing inline seems negligible as this only affects query building, not execution let alone data type binding, but there might be some impact on the compiler? (I couldn't measure any significant difference when compiling code generation integration tests, but maybe, in user projects, there's still a difference).

I don't see why this could be causing backwards compatibility issues in user code. Both keywords aren't really required, unless we need to reflect on a T::class.java type.

Unfortunately, this doesn't seem to fix #13338
