Remove H5detect and H5make_libsettings (#3104)

Removes H5detect and H5make_libsettings from the build and replaces
their functionality with things that don't affect cross-compiling.

H5detect --> floating-point types are now detected on library load
H5make_libsettings --> Moved functionality to a new H5build_settings.c template file
