Usually when we generated stacktraces the process is in error state, so
running hooks may crash the process and prevent meaningfull error report.
Symbolizer, unwinder and pthread are potential source of mallocs.

A while ago we added some code to the sanitizer runtimes for iOS
simulators to allow `atos` (external process) to inspect the sanitized
process during report generation to enable symbolication. This was done
by setting the `__check_mach_ports_lookup` env var early during process
startup which came with a couple of complications.
This workaround is not required anymore and removing it fixes TSan in
the iOS simulator after the new TSan runtime landed.

This is undefined if SANITIZER_SYMBOLIZER_MARKUP is 1, which is the case for
Fuchsia, and will result in a undefined symbol error. This function is needed
by hwasan for online symbolization, but is not needed for us since we do
offline symbolization.

Summary:
This is implemented by adding a `Symbolizer::LateInitializeTools()`
method that iterates over the registered tools and calls the
`LateInitialize()` method on them.
`Symbolizer::LateInitializeTools()` is now called from the various
`Symbolizer::LateInitialize()` implementations.
The default implementation of `SymbolizerTool::LateInitialize()`
does nothing so this change should be NFC.
This change allows `SymbolizerTool` implementations to perform
any initialization that they need to perform at the
LateInitialize stage of a sanitizer runtime init.

See https://reviews.llvm.org/D58620 for discussion, and for the commands
I ran. In addition I also ran
for f in $(svn diff | diffstat | grep .cc | cut -f 2 -d ' '); do rg $f . ; done
and manually updated (many) references to renamed files found by that.
