tests/test-backend-ops : allow regex entries in the -o filter (#29204)

• tests/test-backend-ops : allow regex entries in the -o filter

so far -o only accepted a comma separated list of exact op names or
full test case strings. entries that are not plain op names are now
treated as regexes matched against the op name (e.g. "MUL_MAT.*"),
while plain names keep their exact-matching behavior so that
"-o ADD" does not match ADD_EX etc.

• cont : don't print the FA vec slice log when not needed

• tests/test-backend-ops : reformat the help text

use the same style as the other tools, with separate sections for
modes, options, and examples
