In extended-remote, when GDB connects the target, but target is not
running, the TSVs are not uploaded. When GDB attaches to a process,
the TSVs are not uploaded either. However, GDBserver has some
builtin or predefined TSV to upload, such as $trace_timestamp. This
bug causes $trace_timestamp is never uploaded.

* remote.c (remote_start_remote): Move code to upload tsv
earlier.

* boards/native-extended-gdbserver.exp: Set board_info
'gdb,predefined_tsv'.
* boards/native-gdbserver.exp: Likewise.
* boards/native-stdio-gdbserver.exp: Likewise.
* gdb.server/ext-attach.exp: Load trace-support.exp. Check
uploaded TSVs if target supports tracing.
* gdb.trace/tsv.exp: Check uploaded TSVs if target supports
tracing and target has predefined tsv.
