Introduce a new virtual class StackTracePrinter and an implementation
FormattedStackTracePrinter in preparation of enabling symbolizer markup
for linux.
This change allows us to implement other behaviour under the same api
for StackTracePrinter, for example, MarkupStackTracePrinter.
Reason for revert: A missing header file for the
sanitizer_symbolizer_markup.cpp files.
This was not caught in local builds or pre-merge checks given that to
trigger the error, the code
has to be compiled for Fuchsia.
For this reland I've build for the fuchsia targets as well as linux.
Reason: Not including appropiated headers for
sanitizer_symbolizer_markup.cpp which only runs
in fuchsia.
This reverts commit d4152c5cbfd923d117b2bf24b5b173766e3be0e1.

This fixes the following error:
sanitizer_interface_internal.h:77:7: error: conflicting types for
'__sanitizer_get_module_and_offset_for_pc'
int __sanitizer_get_module_and_offset_for_pc(
common_interface_defs.h:349:5: note: previous declaration is here
int __sanitizer_get_module_and_offset_for_pc(void *pc, char *module_path,
I am getting it on a code that uses sanitizer_common (includes internal headers),
but also transitively gets includes of the public headers in tests
via an internal version of gtest.

This method is like StackTrace::Print but instead of printing to stderr
it copies its output to a user-provided buffer.

`-fno-exceptions -fno-asynchronous-unwind-tables` compiled programs don't
produce .eh_frame on Linux and other ELF platforms, so the slow unwinder cannot
print stack traces. Just fall back to the fast unwinder: this allows
-fno-asynchronous-unwind-tables without requiring the sanitizer option
`fast_unwind_on_fatal=1`

InternalScopedString uses InternalMmapVector internally
so it can be resized dynamically as needed.

Adds a check to avoid symbolization when printing stack traces if the
stack_trace_format flag does not need it. While there is a symbolize
flag that can be turned off to skip some of the symbolization,
SymbolizePC() still unconditionally looks up the module name and offset.
Avoid invoking SymbolizePC() at all if not needed.
This is an efficiency improvement when dumping all stack traces as part
of the memory profiler in D87120, for large stripped apps where we want
to symbolize as a post pass.

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.
