Allow setting parameter values at build time
Allow setting parameter values at build time, enabling additional
compiler optimisations. I measured that e.g. ML_BSSN runs 5% to 10%
faster if its parameters are chosen at build time.
This introduces macros CCTK_PARAMETER${thorn}${parameter}. If unset,
the parameter value is taken from the parameter file (default). If set
at compile time, e.g. via a -D option in CPPFLAGS, this overrides the
parameter database, and DECLARE_CCTK_PARAMETERS will always use this
value.
