src/security/vboot: Set up secure counter space in TPM NVRAM

High Definition (HD) protected content playback requires secure counters
that are updated at regular interval while the protected content is
playing. To support similar use-cases, define space for secure counters
in TPM NVRAM and initialize them. These counters are defined once during
the factory initialization stage. Also add
VBOOT_DEFINE_WIDEVINE_COUNTERS config item to enable these secure
counters only on the mainboard where they are required/used.

BUG=b:205261728
TEST=Build and boot to OS in guybrush. Ensure that the secure counters
are defined successfully in TPM NVRAM space.

On reboot if forced to redefine the space, it is identified as already
defined.
