Adding capability to parse subsections of a byte array in Java bindings (#10489)

* Adding capability to parse subsections of a byte array in Java bindings. (Because Java lacks pointers. Therefore, reading images within a subsection of a byte array is impossible by Java's nature and limitations. Because of this, many IO functions in Java require additional parameters offset and length to define, which section of an array to be read.)

* Corrected according to the review. Previous interfaces were restored, instead internal interfaces were modified to provide subsampling of java byte arrays.

* Adding tests and test related files.

* Adding missing files for the test.

* Simplified the test

* Check was corrected according to discussion. An OutOfRangeException will be thrown instead of returning.

* java: update MatOfByte implementation checks / tests

Add Android Mat constructor with support for native buffer (#10050)

quickly corrected the previous refactoring of features2d: moved from set(SOME_PROP, val) to setSomeProp(val)

CV_CAP_PROP_SUPPORTED_PREVIEW_SIZES_STRING property is not supported
by all VideoCapture backends. Some backends can return 0.0 or -1.0.(cherry picked from commit c41e8006)

New version of Java wrappers' generator uses different wrappers for VideoCapture
on Android and desktop to prevent binary compatibility issues.

Now the features2d class wrappers use composition instead of inheritance.

- enable auto-wrap of VideoCapture;
- minor refactoring of generated code templates.
