Improve CanSupportAEP Error Reporting This change improves the error reporting for the `CanSupportAEP` function. Previously, if the function returned false, it was difficult to determine which requirement was not met. This change adds logging that will list all unmet requirements, making it easier to debug AEP support issues. For Chromium logs, this logging is too much. Therefore, a switch is used and by default the logging is off. ref: https://crrev.com/c/5979208?tab=comments Test: the default presubmit Bug: b/268108262 Change-Id: I7f633cdb63f9cfeb501cd5f134b0ea7874465aed Reviewed-on: https://chromium-review.googlesource.com/c/angle/angle/+/5979292 Reviewed-by: Yuxin Hu <yuxinhu@google.com> Commit-Queue: Shahbaz Youssefi <syoussefi@chromium.org> Reviewed-by: Shahbaz Youssefi <syoussefi@chromium.org>
