Optimize ecma_builtin_helper_def_prop. (#3007)

Browse Source 
This patch removes the ecma_property_descriptor_t structure bitfields and substitutes it with an uint16_t flag field
to reduce the cost of the transformation from/into the ecma_property_flags_t.
Also the is_throw last arguments is embedded to the property descriptor structure during the property defining process to reduce the number of arguments of the function.
