Scott Graham 7faa2ef898 Get CrashpadInfo address via a .note, rather than dynamic symtab 
Embeds the address of g_crashpad_info into a .note section (which is
readable by the generic code to read notes in ElfImageReader).
Unfortunately because the note section is in libclient.a, it would
normally be dropped at link time.  To avoid that, GetCrashpadInfo() has
a reference *back* to that section, which in turn forces the linker to
include it, allowing the note reader to find it at runtime.

Previously, it was necessary to have the embedder of "client" figure out
how to cause `g_crashpad_info` to appear in the final module's dynamic
symbol table.  With this new approach, there's no manual configuration
necessary, as it's not necessary for the symbol to be exported.

This is currently only implemented in the Linux module reader (and I
believe the current set of enabled tests aren't exercising it?) but it
will also be done this way for the Fuchsia implementation of
ModuleSnapshot.
