Subject: [PATCH] [CMake][AIX] Enable CMP0182: Create shared library archives
by default (#155686)
On AIX we prefer to create shared libraries as shared library archives
(i.e. we archive the shared object in a big AR archive) as this is the
standard format on the platform.
There is now a CMake policy that allows us to do this by default, so
opt-in to that behaviour.
