For a code letter D or E aeroplane with an OMGWS of 12 m, how wide must the runway shoulders be on each side to meet the overall width requirement?

The overall width of the runway and its shoulders must be at least 60 m. The section does not specify the individual shoulder width; it only requires that the shoulders extend symmetrically so that the total width (runway + both shoulders) is not less than 60 m.

Which code letter and engine configuration requires a 60 m overall runway-plus-shoulder width for an aeroplane with an OMGWS of 10 m?

Code letter D or E, and code letter F with two- or three-engined aeroplanes (CS ADR-DSN.B.135(a) and (b)).

Does CS ADR-DSN.B.135 apply to aeroplanes with an OMGWS of exactly 15 m?

No. The rule applies to aeroplanes with an OMGWS from 9 m up to but not including 15 m. An OMGWS of exactly 15 m is outside this range.
