[API] Add hb_buffer_[sg]et_not_found_glyph() and --not-found-glyph
...
Instead of using gid=0 when a character is not found in the font,
client can now set a custom value. This is useful for shaper-driven
font fallback and to differentiate that from .notdef glyph.

Remove unneeded buffer clear_output / remove_output calls
...
Made sure clear_output is always paired with swap_buffers.
Trying to see if we can move towards RAII-like buffer iterators
instead of the buffer keeping an iterator internally.

Sucks that has to be specified in this order. But that is what it is for now.
Was only exhibiting problem on C++>=17 since that's when the [[nodiscard]]

To my surprise, saves ~20kb in my build (non-size-optimized) build.
The output_glyph() method is never used in the fast paths, so doesn't
matter if is not fully optimized for the special case it is.

[buffer] Return success status from buffer ops that can fail
...
Previous error-handling philosophy was that user doesn't need to
immediately know whether operation failed. But as can be seen after
we added malloc-failing fuzzing, there's just so many places in the
code that a failure of these operations needs to be mitigated before
further operations. So I'm moving towards returning success here,
and possibly making it nodiscard.
