Jiyong Park 8944432589 Mark libdemangle as vendor_available
The lib is used by libc_malloc_debug_backtrace which is
vendor_available. libc_malloc_debug_backtrace is marked as such because
it is again used by libmemunreachable which is vendor_available.

Bug: 33241851
Test: BOARD_VNDK_VERSION=current m -j libmemunreachable.vendor

Christopher Ferris a11dc8f962 Add a binary to dump demangled names.
Test: Ran the executable and verified names get demangled.
Test: Ran with the -c option to verify it compares demangled names.

Christopher Ferris 9323b7219c Implement a simple demangler.
The purpose of this demangler is to avoid crashes for any string.

- It does one pass and should avoid going past the end of the string.
- The code avoids recursion to minimize the amount of stack required.
- It cannot demangle all mangled names, but it should be able to work
  on nearly all names in normal stack traces.
- If the mangled name is too large, it will stop demangling and return
  as if the name is not a demangled name.

Test: Passes new unit tests.
