Add List[OCTET_STRING] and List[Struct{N, OCTET_STRING] support

[vivien-apple]

Problem

List[OCTET_STRING] or List[Struct{..., OCTET_STRING, }] support is lacking.

Summary of Changes

• Add support for them
• Update gen/ folders

Are these auto-generated? wondering if we need constants for the 31 and 18 values and such.

[vivien-apple]

Those are autogenerated.

[andy31415]

Please move code that does not need to be generated into a separate h/cpp file and add unit tests.

[woody-apple]

@vivien-apple sorry needs restyle

[andy31415]

I would name this buffer-byte-span.h or zap-byte-span.h, to try to not use support/helper/util/tools in naming.
