[testsuite,arm] target-supports.exp: Add arm_fp_dp_ok effective-target
Some tests require double-precision support, but the existing
arm_fp_ok effective-target only checks if hardware floating-point is
available, not what level. So this patch adds a new arm_fp_dp_ok
effective-target to check that double-precision is supported.
