ANGLE commit id is missing in angle\id\commit.h

Prior to Qt 5.12-beta3, the ANGLE commit ID was stored in qtbase\src\3rdparty\angle\src\id\commit.h
(e.g.:
#define ANGLE_COMMIT_HASH "8613f4946861"
#define ANGLE_COMMIT_DATE "2016-02-11 19:53:41 +0000"
)

In Qt 5.12-beta3, the ANGLE was updated to some newer but unknown version:

• directory layout was changed
• commit id should be in qtbase\src\3rdparty\angle\id\commit.h
• but the defines are not filled:

#define ANGLE_COMMIT_HASH "unknown hash"
#define ANGLE_COMMIT_DATE "unknown date"

it is very inconvenient not to know which version is used
