[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.

[buffer] Fix order of HB_INTERNAL HB_DISCARD

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]]

[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.
