[PATCH i-g-t v5 1/4] tests/intel/kms_pm_dc: Add time unit macros and update delay calculation

[Naladala Ramanaidu]

This change improves code readability and consistency in time unit
conversions. Replace MSECS with more granular time units: SEC, MSEC,
and USEC. Update the delay calculation in test_deep_pkgc_state to use
the new MSEC macro.
