docs: Remove mention of Perf Sample Flamegraph flag This flag was turned on by default long ago in aosp/2045272 so the user no longer needs to explicitly enable it. Since the user no longer needs to explicitly enable the flag, remove those instructions from the documentation. Change-Id: Ib25981440855beab56ccbd935b0360030c886dec
