Paweł Marczewski 09c6307631 [Pal] Clean up GDB configuration
- Extract parts that are common for all hosts
- Remove some outdated/unnecessary options, we should now be
  closer to default configuration
- Disable libthread_db loading (does not work and crashes GDB 9.2)
- Disable pagination when loading debug maps

# This is how we detect whether we're installed or running from inside git repo.
# If unchanged (i.e., if this reads IN_GIT between "at" characters), this is an
# ordinary string and test -n "$IN_GIT" is true. But when installing, this is
# rewritten using meson's configure_file() function to an empty string and the
# else branch is taken. See also: ./meson.build and
# https://mesonbuild.com/Reference-manual.html#configure_file.
