* Handle allocator propagation in basic_memory_buffer::move
Update `basic_memory_buffer::move` to respect `propagate_on_container_move_assignment`allocator trait.
If the allocator should not propagate and differs from the target's allocator,
fallback to copying the buffer instead of transferring ownership.
This avoids potential allocator mismatch issues and ensures exception safety.
* Add test cases for the updated move ctor
- Added two test cases `move_ctor_inline_buffer_non_propagating` and `move_ctor_dynamic_buffer_non_propagating`
- Added `PropageteOnMove` template parameter to `allocator_ref` class to be compatible with the old test cases
- `allocator_ref` now implements `!=` and `==` operators
* all GTest/GMock files moved to `test/gtest` directory
* `CMakeLists.txt` created in `test/gtest` from `CMakeLists.txt` in `test`
* GTest/GMock target in CMake renamed to `gtest` (was `gmock`)
* CMake `gtest` target updated to export includes as "gtest/gtest.h" or "gmock/gmock.h" only
* includes in tests updated: "gtest.h" -> "gtest/gtest.h", "gmock.h" -> "gmock/gmock.h"
* removed duplications of `target_include_directories` for GTest/GMock directories (CMake manages them)

Array is split into an abstract Buffer class and a concrete MemoryBuffer class. BasicWriter now does all memory allocation through a Buffer object. Subclasses of BasicWriter may use different buffer types. The new BasicMemoryBuffer class uses the default MemoryBuffer.
