Previously, the DSA segment size always started with 1MB and grew up to DSA_MAX_SEGMENT_SIZE. It was inconvenient in certain scenarios, such as when the caller desired a soft constraint on the total DSA segment size, limiting it to less than 1MB. This commit introduces the capability to specify the initial and maximum DSA segment sizes when creating a DSA area, providing more flexibility and control over memory usage.
