This patch changes the way we load a crash report into a scripted
process by creating a empty target.

To do so, it parses the architecture information from the report (for
both the legacy and json format) and uses that to create a target that
doesn't have any executable, like what we do when attaching to a process.

For the legacy format, we mostly rely on the `Code Type` line, since the
architure is an optional field on the `Binary Images` sections.

However for the json format, we first try to get the architecture while
parsing the image dictionary if we couldn't find it, we try to infer it
using the "flavor" key when parsing the frame's registers.

If the architecture is still not set after parsing the report, we use
the host architecture, as a fallback.
