Fixes #10438
issue found by clusterfuzz/ossfuzz

The dest was getting a copy of the src structure which contained a pointer that should point to an offset inside itself - because of the copy it was pointing to the original structure.

The setup for a ctx is mainly done by the initkey method in the PROV_CIPHER_HW structure. Because of this it makes sense that the structure should also contain a copyctx method that is use to resolve any pointers that need to be setup.

A dup_ctx has been added to the cipher_enc tests in evp_test. It does a dup after setup and then frees the original ctx. This detects any floating pointers in the duplicated context that were pointing back to the freed ctx.

From providers/{common,default}/ to providers/implementations/

Except for common code, which remains in providers/common/ciphers/.
However, we do move providers/common/include/internal/ciphers/*.h
to providers/common/include/prov/, and adjust all source including
any of those header files.
