Add AbstractClassAssert#is(Not)Primitive()

[onacit]

Feature summary

The AbstractClassAssert lacks with is(Not)Primitive().

Example

assertThat(int.class).isPrimitive();
assertThat(String.class).isNotPrimitive();

There is already workarounds for the case, I know.

assertThat(c.isPrimitive()).isTrue();

I just found a case regarding the .as(...).

for (Field file : findSomeSpecificFields()) {
    assertThat(field.getType().isPrimitive())
        .as("@NullableBySpecification on primitive field: %s", field)
        .isFalse();
}

which may be more fluent,

for (Field file : findSomeSpecificFields()) {
    assertThat(field.getType())
        .as("%s annotated with @NullableBySpecification, field)
        .isNotPrimitive();
    //  '...Class#field annotated with @NullableBySpecification should not be primitive.
}

Hi @joel-costigliola
Could I take this one? 😃

[scordio]

Go for it, @ManuelG28!

[onacit]

Oh. I just found myself, again, expecting assertThat(clazz).isPrimitive().
@ManuelG28 Is your PR still working in progress?

[scordio]

Sorry, #2722 slipped under our radar.

I've added it to 3.25.0.
