This patch adds support for recording BuildIds usng the sanitizer
ListOfModules API. We add another entry to the SegmentEntry struct and
change the memprof raw version.

The memprof profiles and binaries need to be updated in case of version
updates. This change adds three scripts for llvm-profdata, clang and
llvm tests where memprof profiles are used as inputs. Also update the
tests, profiles and binaries in this change. Change based on the review
suggestions in D145023.

This change replaces the binary profiles and executables used for
testing the memprof profile reader with tests where the profiles are
generated on the fly. This reduces toil when the profile version
changes. The tests are moved from tools/llvm-profdata to
compiler-rt/test/memprof due to the following reasons:
1. Adding dependency on memprof lit.cfg.py for llvm-profdata is
preferable to adding a dependency on compiler-rt for llvm/test.
2. All the tests can now be run with `ninja check-memprof`.

Track min/max/avg access density (accesses per byte and accesses per
byte per lifetime second) metrics directly during profiling. This allows
more accurate use of these metrics in profile analysis and use, instead
of trying to compute them from already aggregated data in the profile.
This required regenerating some of the raw profile and executable inputs
for a few tests. While here, make the llvm-profdata memprof tests more
resilient to differences in things like memory mapping, timestamps and
cpu ids to make future test updates easier.

This reverts commit dbf47d227d080e4eb7239b589660f51d7b08afa9.
Reapply https://reviews.llvm.org/D116784 now that
https://reviews.llvm.org/D118413 has landed with a couple of fixes:
* fix raw profile reader unaligned access identified by ubsan
* fix windows build by using MOCK_CONST_METHOD3 instead of MOCK_METHOD.
This change extends the RawMemProfReader to read all the sections of the
raw profile and symbolize the virtual addresses recorded as part of the
callstack for each allocation. For now the symbolization is used to
display the contents of the profile with llvm-profdata.
