The `getDebuggingInfo` function relies on `programCounters` being a
NULL terminated list. However, none of the usage actually adds NULL...
- In the path that passes `getProgramCounters` result into
`getDebuggingInfo`, no explicit 0 value is added to `result`.
In practice, there happens to be a 0 there very frequently,
but it is not guaranteed (`env MallocScribble=1`), and even
if it is not there the implementation often continues to work
when processing the extra garbage data, silencing the problem.
- In the path from Nim `addDebuggingInfo` (`system/stacktraces.nim`),
the `programCounters` list is constructed by Nim logic and also
does not add a 0 value to the list. This means that even if we fix
`getProgramCounters` to produce NULL terminated list, other usage
is still broken, and outside the control of this library.
Therefore, remove the NULL terminator logic and pass length explicitly
while retaining any early loop exits when encountering 0 for compat.
Also fix some memory leaks in error conditions.

This extends the build error message when CMake is not installed with a
macOS specific hint to install it using Homebrew, in line with how other
Status components report missing system dependencies.
libbacktrace bumped to the latest comit in the "master" branch of https://github.com/ianlancetaylor/libbacktrace
libunwind manually copied from https://github.com/llvm/llvm-project -
commit f749550cfe9f0bf2364abb2139835348587062ed - on top of which I
disabled a dependency on "../libcxx" that only makes sense in the LLVM
monorepo.
Allow separating stack unwinding and program counter collection from the
more expensive step of getting the associated debugging info for each
program counter.
This is useful for implementing efficient backtraces for exceptions - a
scenario in which you add a new backtrace each time an exception is
re-raised, but you rarely need to print them (usually when that
exception is uncaught).
