  Remove SharedMemory::adopt

Reviewed by Kimmo Kinnunen and Fujii Hironori.

Use the updated methods in `Win32Handle` to implement
`Data::tryCreateSharedMemory` without directly calling into
`DuplicateHandle`. This code was the only place calling
`SharedMemory::adopt` outside of `SharedMemory.cpp`. Move the contents
of it into `SharedMemory::map` and remove this Window's only method.

* Source/WebKit/NetworkProcess/cache/NetworkCacheDataCurl.cpp:
(WebKit::NetworkCache::Data::tryCreateSharedMemory const):
* Source/WebKit/Platform/SharedMemory.h:
* Source/WebKit/Platform/win/SharedMemoryWin.cpp:
(WebKit::SharedMemory::map):
(WebKit::SharedMemory::adopt): Deleted.
