  Log Message:
  -----------
  [memprof] Use -memprof-runtime-default-options to set options during compile time (#118874)

Add the `__memprof_default_options_str` variable, initialized via the
`-memprof-runtime-default-options` LLVM flag, to hold the default options string
for memprof. This allows us to set these options during compile time in
the clang invocation.

Also update the docs to describe the various ways to set these options.
