WebDriver: matched capabilities should include setWindowRect

Reviewed by Carlos Alberto Lopez Perez.

Source/WebDriver:

Handle setWindowRect in capabilities. It's always true for GTK and false for WPE.

* Capabilities.h:
* WebDriverService.cpp:
(WebDriver::WebDriverService::parseCapabilities const):
(WebDriver::WebDriverService::matchCapabilities const):
(WebDriver::WebDriverService::newSession):
* gtk/WebDriverServiceGtk.cpp:
(WebDriver::WebDriverService::platformCapabilities):
* wpe/WebDriverServiceWPE.cpp:
(WebDriver::WebDriverService::platformCapabilities):

WebDriverTests:

Change the bug number of test imported/w3c/webdriver/tests/sessions/new_session/response.py::test_resp_data,
since now it's failing due to missing timeouts value.

* TestExpectations.json:
