Improve error message for MaxAllocSize overrun in accumArrayResult. Before, if you went past about 64M array elements in array_agg() and allied functions, you got a generic "invalid memory alloc request size" error. This patch replaces that with "array size exceeds the maximum allowed", which seems more user-friendly since it points you to needing to reduce the size of your array result. (This is the same error text you'd get from construct_md_array in the event of overrunning the maximum physical size for the finished array.)
Per question from Shaozhong Shi. Since this hasn't come up often, I don't feel a need to back-patch.
