  Log Message:
  -----------
  [lldb] Add a corefile fuzzer (#225103)

Fuzzes the metadata parser when LLDB opens a corefile for Mach-O
and ELF.

The fuzzer writes input data to a tempfile and loads it through
`Process::LoadCore()`, the same way `target create --core` does.
It initializes both the macOS and Linux host platforms so the
core-load path runs regardless of which of the two OSes the fuzzer
itself is built on.

`lldb-target-fuzzer` does not reach any of this. It only calls
`SBDebugger::CreateTarget`, which builds a Target and its executable
Module; identifying that module parses the Mach-O/ELF header and
load/section commands, but never calls `Process::LoadCore`.
