alsa_conformance_test: Add merge_threshold_sz test arg

When ring DMA runs in burst mode, the merge window needs taking
burst periods into consideration. Without the right merge_threshold_sz,
the overall test results could be interpreted as false positive. Thus
adding an option to supply merge_threshold_sz as input, when not
provided, this value is computed on the fly from dry run.

TEST=alsa_conformance_test -P hw:0,0 --merge_threshold_sz=48
