Docs/mm/damon/design: remove 'Programmable Modules' section in favor of 'Modules' section

'Programmable Modules' section provides high level descriptions of the
DAMON API-based kernel modules layer.  But 'Modules' section, which is at
the end of the document, provides every detail about the layer including
that of 'Programmable Modules' section.

Since the brief summary of the layers at the beginning of the document has
a link to the 'Modules' section, browsing to the section is not that
difficult.  Remove 'Programmable Modules' section in favor of 'Modules'
section and reducing duplicates.

-Core layer of DAMON is implemented as a framework, and exposes its application
