cmd: Update the memory-search command
Add various fixes and improvements to this command that were missed in the original version. Unfortunately I forgot to send v2. - Fix Kconfig name - Use a separate variable for the remaining search length - Correct a minor bug - Move into a separate test suite - Add -q flag to the 'quiet' test to test operation when console is enabled - Enable the feature for sandbox Signed-off-by: Simon Glass <sjg@chromium.org>
