build: Switch default meson buildtype to 'debugoptimized'

The meson 'debug' buildtype defaults to '-O0 -g' which misses
some important compiler warnings (as of gcc-13). While there's
no universal solution, the 'debugoptimized' buildtype supplies
'-O2 -g' that appears to be a reasonable compromise for having
important compiler warnings by default.
