[ot-shape] Don't verify buffer if shaping failed

Fixes all of fuzzing verify failures, which were result of buffer failure
on super-long results, which fails unsafe-to-break because shorter strings
don't fail shaping.

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] 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.

[buffer/set/map] Move immutable check only to C API boundary
...
The immutable objects are a concept only enforced by the C API.
So move checks only to that region.
This does assume that the rest of the code is careful not getting
into these internal methods on immutable objects, which something
we do, but have no way of enforcing (currently).
