media: Support persistent hardware secure decryption disabling

This CL adds a new pref in "Local State" to keep track of past times
when hardware secure decryption was disabled. To avoid repeated playback
errors after each browser restart, this new pref is checked at browser
start time and hardware secure decryption should remain disabled if it
was disabled explicitly in the last 7 days. We will add metrics here
and refine the detailed disabling algorithm later.

Manually tested by triggering multiple playback errors and make sure
hardware secure decryption should remain disabled after browser restart.

Bug: 1296219
Test: See above
