The cached X509_LOOKUP method data is no longer just the URI, but now
includes the OSSL_STORE_CTX pointer, and required parameters to reopen
the URI at any time.  cache_objects() is modified to handle this, and
only (re)open the URI when it wasn't previously opened, or when it was
closed by an earlier call.

This way, we can call OSSL_STORE_open_ex() in by_store_ctrl_ex(), and
get to see possible errors when the URI is loaded.

This assumes that if the URI could be opened once, it can be opened
again.

Fixes #27461

It was used to pass libctx and propq, which would override the
corresponding values passed to by_store_ctrl_ex().  This wasn't
really reasonable to do either way, as it could potentially be a
surprise to the user, who can reasonably expect that the URI is
opened with the libctx and propq that was passed with the URI, and
not with those passed later.
