pkg/compiler: make buffer alias to ptr[array[int8]]
Ptr type has special handling of direction (pointers are always input).
But buffer type missed this special case all the time.
Make buffer less special by aliasing to the ptr[array[int8]] type.
As the result buffer type can't have optional trailing "opt" attribute
because we don't have such support for templates yet.
Change such cases to use ptr type directly.
Fixes #1097
