[lldb] Clear thread-creation breakpoints in ProcessGDBRemote::Clear (#134397)

Currently, these breakpoints are being accumulated every time a new
process if created (e.g. through a `run`). Depending on the
circumstances, the old breakpoints are even left enabled, interfering
with subsequent processes. This is addressed by removing the breakpoints
in ProcessGDBRemote::Clear

Note that these breakpoints are more of a PlatformDarwin thing, so in
the future we should look into moving them there.
