G-API: A quick (but not very dirty) value-initialization support GMat
Feb 21, 2024
- Added more tests;
- Added a negative test on GComputation with no inputs.
Currently explicitly marked as throwing exception (tuned code not
to crash in this case). Supporting running graphs like this will
be added in a separate PR (a differnt feature)

G-API: A quick value-initialization support GMat opencv#25055
This PR enables `GMat` objects to be value-initialized in the same way as it was done for `GScalar`s (and, possibly, other types).
- Added some helper methods in backends to distinguish if a certain G-type value initialization is supported or not;
- Added tests, including negative.
Where it is needed:
- Further extension of the OVCV backend (opencv#24379 - will be refreshed soon);
- Further experiments with DNN module;
- Further experiments with "G-API behind UMat" sort of aggregation.
In the current form, PR can be reviewed & merged (@TolyaTalamanov please have a look)
