[SRU][N:gke][PATCH 075/106] perf arm-spe: Rename arm_spe__synth_data_source_generic()

From: Leo Yan <leo.yan at arm.com>

BugLink: https://bugs.launchpad.net/bugs/2117098

The arm_spe__synth_data_source_generic() function is invoked when the
tool detects that CPUs do not support data source packets and falls back
to synthesizing only the memory level.

Rename it to arm_spe__synth_memory_level() for better reflecting its
purpose.
