until we can automatically fall back to p/P if g/G are not supported;
it looks like there is a bug in debugserver's g/G packets taht needs
to be fixed, or debugserver should stop supporting g/G until that bug
is fixed. But we need lldb to be able to fall back to p/P correctly
for that to be a viable workaround.
Following up on https://reviews.llvm.org/D62221, this change introduces
the settings plugin.process.gdb-remote.use-g-packet-for-reading. When
they are on, 'g' packets are used for reading registers.
Using 'g' packets can improve performance by reducing the number of
packets exchanged between client and server when a large number of
registers needs to be fetched.

Summary:
This is a bit more explicit, and makes it possible to build LLDB without
varying the -I lines per-directory.
(The latter is useful because many build systems only allow this to be
configured per-library, and LLDB is insufficiently layered to be split into
multiple libraries on stricter build systems).
(My comment on D65185 has some more context)
