Move the wrenIsBool and wrenIsObjType function definitions from wren_value.c into wren_value.h as inline functions, eliminating function call overhead. Also relocate OBJ_VAL macro definition to appear before its first use in the header and add inline for wrenObjectToValue. This yields 3-13% speedup across benchmarks (binary_trees, delta_blue, fib, for, method_call).
