Record trailing line dbg instructions (#2926)

There is nothing in the spir-v spec that says the last
instructions in a module cannot be OpLine or OpNoLine.
However, the code that parses the module will simply drop
these instructions.

We add code that will preserve these instructions.

Strip-debug-info is updated to remove these instructions.
