Subject: [PATCH v2 1/7] perf arm-spe: Rename arm_spe__synth_data_source_generic()

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.
