Size should be calculate after confirm the final start address

[fredlee12001]

Description

The final size maybe wrong if we caculate the size before start address.
Since the start address may shift after align operation, then the final size/post address should shift as well.

This looks like a correct fix. Before this comes in, would you mind posting a before and after log of the region output? I'm specifically interested in the following part, which is found at the top of the log when running mbed compile from a project that uses a bootloader:

$ mbed compile
[mbed] Working path "C:\Users\bridan01\onedrive_arm\Documents\dev\mbed-cloud-client-example" (program)
