gdbserver: remove the static_tracepoint enum value

As a continuation of the previous patches that remove UST from
gdbserver, remove the `static_tracepoint` enum value from
`tracepoint_type` and all the associated code.

Now that the last use of `write_e_static_tracepoints_not_supported`
is gone, also remove that function.

The handling of the 'S' option, where the `static_tracepoint` enum
value was being used, is removed completely, because recognizing that
option makes sense only when static tracepoint support is announced.

This patch is easier to view with "git show -w".
