  [BOLT] Support profile density with basic samples (#137644)

For profile with LBR samples, binary function profile density is
computed as a ratio of executed bytes to function size in bytes.

For profile with IP samples, use the size of basic block containing the
sample IP as a numerator.

Test Plan: updated perf_test.test
