The PR doesn't add OpCooperativeMatrixApplyFunctionINTEL instruction as
it's still experimental and not properly tested E2E.
The PR also fixes few bugs in the related code:
1. CooperativeMatrixMulAddKHR optional operand must be literal, not a
constant;
2. Fixed available capabilities table creation for a case, when a single
extension adds few capabilities, that occupy not contiguous op codes.
