Fix AudioParam.linearRampToValueAtTime() formula to match specification
https://bugs.webkit.org/show_bug.cgi?id=215904

Reviewed by Darin Adler.

LayoutTests/imported/w3c:

Rebaseline WPT tests now that more checks are passing or now that they keep passing/failing with
slightly different values.

Source/WebCore:

Fix AudioParam.linearRampToValueAtTime() formula to match specification:
- https://www.w3.org/TR/webaudio/#dom-audioparam-linearramptovalueattime

We were using a different formula to compute the value and this was causing us
to fail some web platform tests.

No new tests, rebaselined existing tests.

(WebCore::AudioParamTimeline::valuesForTimeRangeImpl):

+        Fix AudioParam.linearRampToValueAtTime() formula to match specification:
+        - https://www.w3.org/TR/webaudio/#dom-audioparam-linearramptovalueattime
+
+        We were using a different formula to compute the value and this was causing us
+        to fail some web platform tests.
+
+        No new tests, rebaselined existing tests.
