Use EXPECT_EQ directly instead of EXPECT_STREQ in the tests of core/css

As the first step to deprecate WTF::CString, the bug has suggested replacing
EXPECT_STREQ with EXPECT_EQ. This CL replaces EXPECTED_STREQ with EXPECT_EQ
in the cases of converting WTF::String to const char* in order to use
EXPECTE_STREQ.
