gdb/testsuite/gdb.base/break.exp: split test_break_silent_and_more

Browse Source 
This one is a bit tricky.  The clear tests seem to depend on the various
breakpoints that have been set before, starting with the "silent"
breakpoints.  So, move all this in a single chunk, it can always be
split later if needed.
