generalize tolerances for convolver channelCountMode tests

This is essentially a merge of
https://github.com/web-platform-tests/wpt/pull/11935 with
https://github.com/web-platform-tests/wpt/pull/21493.

For downMixTest() in convolver-response-1-chan.html, channelCount is 2 and so
channelCountMode: 'explicit' results are expected to match default
'clamped-max' results when the number of input channels is >= 2.

Coefficients for down-mixing 5.1 mean the maximum expected amplitude differs
between mono and stereo output as in convolver-response-2-chan.html.

Depends on D77969
