Xcode: Set build product locations using CONFIGURATION_BUILD_DIR

Since commit 59a2265576 (Xcode: Use EFFECTIVE_PLATFORM_NAME reference in
ComputeOutputDir, 2011-08-12, v2.8.6~43^2~1) we can now set the build
products path using `CONFIGURATION_BUILD_DIR` unconditionally because we
compute the correct value even when using `EFFECTIVE_PLATFORM_NAME`.
This avoids relying on `SYMROOT` to locate the build products.

Issue: #22550
