Execution Tests: Skip SM6.9 double precision tests when double precision not supported (#8117)

This PR updates the exec tests to skip in non-hlk environment for double
precision SM6.9 tests when the device doesn't have double precision
support.

Verified via short circuiting the logic in doesDeviceSupportDouble.

Resolves #7523
