Should it send the `bool` passed into this function, even though it is "unused"?

IIRC this `bool` only exists to differentiate this `sendResponse` from the `sendResponse` in <https://trac.webkit.org/browser/trunk/Source/JavaScriptCore/inspector/cocoa/DeprecatedInspectorValues.cpp#L195>.

This also matches the behavior before r266885.

This seems to have regressed again... 

STR:
 1. build-webkit --debug
 2. run-safari --debug 

Expected: Safari to start up

Actual:
```
Starting SafariForWebKitDevelopment with DYLD_FRAMEWORK_PATH set to point to built WebKit in /Users/mcaceres/dev/WebKit/WebKitBuild/Debug.

Marcos, this is fallout from JavaScriptCore breaking ABI compatibility. For this to not be hit will require the changes in WebInspector.framework to be in your system library. This won't happen until you update Safari. The fix for this should be in Safari 14.1 beta, which is available via here: https://developer.apple.com/safari/download/

[Marcos Caceres]

Thanks, BJ. Appreciate the update! I'll give the beta a go.
