`_remote_debugging`: Degrade gracefully reads instead of failing the whole read completely

Bug report

Bug description:

The implicit problem found in https://discuss.python.org/t/tachyon-97-error-rate/107619 and, subsequently, in #151022 and #151036 is that we're raising exceptions and discarding the whole sample, when we could degrade gracefully and keep most of the information.

There are are many limits from which we can recover gracefully, by truncating the data. In particular: funcnames, filenames, locations, but also some temporary reads from the target and other walking limits.

Raising exceptions causes very high error rates, when it doesn't really need to be the case. Also, we really don't know what might be the limits found in the real apps.

CPython versions tested on:

CPython main branch
