  [JITLink][MachO] Fix alignment bug in the c-string literal section graphifier.

This function had been assuming a 1-byte alignment, which isn't always correct.
This commit updates it to take the alignment from the __cstring section.

The key change is to the createContentBlock call, but the surrounding code is
updated with clearer debugging output to support the testcase (and any future
debugging work).
