Add tracing support for the SBAF IFS tests, which may be useful for
debugging systems that fail these tests. Log details like test content
batch number, SBAF bundle ID, program index and the exact errors or
warnings encountered by each HT thread during the test.

In Field Scan test image files are named in ff-mm-ss-<batch02x>.scan
format. Current trace output, prints the batch number in decimal format.
Make it easier to correlate the trace line to a test image file by
showing the batch number also in hex format.
Add 0x prefix to all fields in the trace line to make the type explicit.

Add the current batch number in the trace output. When there are
failures, it's important to know which test content resulted in failure.

Enable the trace function on all HT threads. Currently, the trace is
called from some arbitrary CPU where the test was invoked.
This change gives visibility to the exact errors as seen by each
participating HT threads, and not just what was seen from the primary
thread.
Sample output below.

Width of chunk related bitfields is ACTIVATE_SCAN and SCAN_STATUS MSRs
are different in newer IFS generation compared to gen0.
Make changes to scan test flow such that MSRs are populated
appropriately based on the generation supported by hardware.
Account for the 8/16 bit MSR bitfield width differences between gen0 and
newer generations for the scan test trace event too.
