Bug #48317 cannot build innodb as static library.

The problem here is that the latest innodb push contains
both MYSQL_STORAGE_ENGINE(INNOBASE) and MYSQL_STORAGE_ENGINE(INNOBASE)
in the same CMakeLists.txt, to make the resulting library
ha_innodb.dll, instead of ha_innobase.dll.

Using multiple MYSQL_STORAGE_ENGINE within the same  CMakeLists.txt
conflicts with the fix for the bug Bug #47795 "CMake, storage engine
name different from directory name". Top-level CMakeLists.txt now 
parses storage engine's  CMakeLists.txt to extract engines name from 
MYSQL_STORAGE_ENGINE().

For innodb, it concludes that there is not storage engine named
INNOBASE, hence WITH_INNOBASE_STORAGE_ENGINE has no effect.

The fix is to use SET_TARGET_PROPERTIES(... PROPERTIES OUTPUT_NAME ...),
instead of renaming the engine to have plugins named ha_innodb.dll.
