arch/x86: Use TSC_MONOTONIC_TIMER for timestamps

Implementations with TSC_MONOTONIC_TIMER can take benefit
of the generic implementations of timestamp_get() and
timestamp_freq_tick_mhz() in lib/timestamp.c.

The precision of generated timestamps table is reduced
to microseconds with this commit.

The reasoning for keeping COLLECT_TIMESTAMPS_TSC is that
family10h-15h monotonic timer and LAPIC_MONOTONIC_TIMER
currently do not run in all stages.
