BUG#11759349 - 51655: CREATE TABLE IN MEMORY ENGINE DOESN'T STORE

                      CREATE_TIME IN INFORMATION_SC

It was impossible to determine MEMORY table creation time,
since it wasn't stored/exposed.

With this patch creation time is saved and it is available via
I_S.TABLES.CREATE_TIME.

Note: it was decided that additional analysis is required before
implementing UPDATE_TIME. Thus this patch doesn't store UPDATE_TIME.
