  [tooling] Make the last-built tree tiebreaker sanitizer-aware
https://bugs.webkit.org/show_bug.cgi?id=319001
rdar://181851997

Reviewed by Sammy Gill.

The last-built tiebreaker which landed as https://commits.webkit.org/316853@main
looked at cmake-mac/<Configuration>, but a CMake
sanitizer build lands in cmake-mac/ASan or cmake-mac/TSan. So a most-recent
CMake ASan/TSan build was never detected and the tool fell back to Xcode.

Resolve the CMake tree the same way determineConfigurationProductDir() does,
so the auto-detect and the tiebreaker both inspect the tree a sanitizer build
actually populates. Xcode is unchanged (ASan is toggled within Debug/Release).

* Tools/Scripts/webkitdirs.pm:
(determineIsCMakeBuild):
* 
Tools/Scripts/webkitperl/webkitdirs_unittest/determineIsCMakeBuildLastBuiltASan.pl:
 Added.
