Series perf arm-spe: Enable timestamp | expand

In current code, it assigns the arch timer counter to the synthesized
samples Arm SPE trace, thus the samples don't contain the kernel time
but only contain the raw counter value.

To fix the issue, this patch converts the timer counter to kernel time
and assigns it to sample timestamp.
