cmake: add control over inline source code disassembly

By default, the generated disassembly file (i.e: the .lst
file) also contains inline source code. This has the
potential to become problematic when attempting to compare
the generated .lst files accross platforms since they may
differ for various reasons. As such, add the option to
control whether the disassembly file should contain inline
source code or not.

The need for this patch was sparked by the differences
observed in the generated .lst file for Linux and Windows
in one of SOF's CI jobs (details in thesofproject/sof/issues/9034),
which were caused by the addition of the inline source code.
With this, we can keep testing for reproducible builds while
not having to deal with differences in the .lst files caused
by things such as having ".." include paths.
