Add a ParamConverterProvider for array support

[jbescos]

Relates to this: jakartaee/rest#890

Primitive types are not supported. That is said here in the part 'T satisfies 1, 3 or 4 above.':
jakartaee/rest#891

shouldn't it be for jakartified spec only?

Please make tests for cases 3 and 4, too.
for 4 for instance:

    public static class ArrayTestBean {
        private final String value;

        private ArrayTestBean(String value) {
            this.value = value;
        }

        public static ArrayTestBean fromString(String bean) {
            return new ArrayTestBean(bean);
        }

        @Override
        public String toString() {
            return value;
        }
    }

        @Path("/queryBeanArray")
        @GET
        public Response queryBeanArray(@QueryParam(PARAM_NAME) ArrayTestBean[] data) {
            StringBuilder sb = new StringBuilder(data.length);
            for (ArrayTestBean d : data) {
                sb.append(d);
            }
            return Response.ok(sb.toString()).build();
        }

        @Path("/queryBeanList")
        @GET
        public Response queryBeanList(@QueryParam(PARAM_NAME) List<ArrayTestBean> data) {
            StringBuilder sb = new StringBuilder(data.size());
            for (ArrayTestBean d : data) {
                sb.append(d);
            }
            return Response.ok(sb.toString()).build();
        }

    @Test
    public void queryBean() {
        Response expected = target("/test/queryBeanList").queryParam(PARAM_NAME, "1", "2").request().get();
        Response arrayResponse = target("/test/queryBeanArray").queryParam(PARAM_NAME, "1", "2").request().get();
        verifyStr(expected, arrayResponse);
    }

Why is this test in this package? Assumingly it should be next to similar tests, in tests/e2e-server perhaps?

[jbescos]

Good to know. By default I was adding tests in JDK connector.

[jansupol]

There is no defaultValue param

For 3.1, it would be a MUST. For 2.x, it is an enhancement.
