Fix export_to_cl_image issue in the fp16 GeMM implementation

- The issue affects Fp16 GeMM on Arm® Mali™-G78
- The issue was caused by a missing fallback implementation for the
case when export_to_cl_image cannot be used
- The new implementation fixes this issues and make the GeMM
implementation for M=1 also faster (4-5% on various networks with fully
connected at the end of the model)
- This patch also enables the H0=0 case in the GeMM examples

Resolves COMPMID-5812, COMPMID-5688, and COMPMID-6147
