Subject: fixup: update the line layout cache when changing the tab draw mode

This is important when caching the line layout, so that changing the
tab draw mode to SCTD_CONTROLCHAR will actually change the identations.
This is already in upstream Scintilla as part of 7621fda67d13735836c6f050d1eec8c691a68292.

d4fa2014808092ddfaa0c97c1755af87a182be6b will not be merged upstream
and should be refactored when rebasing on the next Scintilla version
to keep down the number of touched lines.
