Jesús (gsus) Lapastora bc70144df1 LibJIT: Enable registering JITted objects into GDB ...

The new JIT::GDB namespace enables registering JITted objects into GDB
dynamically.

Its clients just have to ensure the memory they give to
`register_into_gdb` is in a format that GDB can understand, either by
generating an object file in memory with debug info + symbols or by
registering a custom debug info parser.
None of these are implemented by this API; it only implements the
registering part and lets the client to choose the data format.

Things to take into account from v8's docs, some of which we may
improve: https://v8.dev/docs/gdb-jit#known-limitations
