      gdb/testsuite: change newline patterns used in gdb_test

It was pointed out in PR gdb/30403 that the same patterns can be found
in other lib/gdb.exp procs and that it would probably be a good idea
if these procs remained in sync with gdb_test.  Actually, the bug
specifically calls out gdb_test_multiple when using with '-wrap', but
I found a couple of other locations in gdb_continue_to_breakpoint,
gdb_test_multiline, get_valueof, and get_local_valueof.

In all these locations one or both of the following issues are
addressed:

  1. A leading pattern of '[\r\n]*' is pointless.  If there is a
  newline it will be matched, but if there is not then the testsuite
  doesn't care.  Also, as expect is happy to skip non-matched output
  at the start of a pattern, if there is a newline expect is happy to
  skip over it before matching the rest.  As such, this leading
  pattern is removed.

  2. Using '\[\r\n\]*$gdb_prompt' means that we will swallow
  unexpected blank lines at the end of a command's output, but also,
  if the pattern from the test script ends with a '\r', '\n', or '.'
  then these will partially match the trailing newline, with the
  remainder of the newline matched by the pattern from gdb.exp.  This
  split matching doesn't add any value, it's just something that has
  appeared as a consequence of how gdb.exp was originally written.  In
  this case the '\[\r\n\]*' is replaced with '\r\n'.

I've rerun the testsuite and fixed the regressions that I saw, these
were places where GDB emits a blank line at the end of the command
output, which we now need to explicitly match in the test script, this
was for:

  gdb.dwarf2/dw2-out-of-range-end-of-seq.exp
  gdb.guile/guile.exp
  gdb.python/python.exp

Or a location where the test script was matching part of the newline
sequence, while gdb.exp was previously matching the remainder of the
newline sequence.  Now we rely on gdb.exp to match the complete
newline sequence, this was for:

  gdb.base/commands.exp
