Subject: [PATCH] fix(@angular/build): direct check include file exists in
 unit-test discovery

When discovering unit-test files, the `include` option values that are
not dynamic patterns will now be checked directly if they exist on the
file system. This avoids glob calls for specific files and helps avoid
Windows pathing issues with glob syntax.
