gdb, btrace: remove record_btrace_target::supports_*()

Let's not introduce support for breakpoint types the target beneath does
not support, even though we could while replaying.

Otherwise, users may set breakpoints during replay that then couldn't be
inserted into the target when switching back to recording.
