  1. write/unit: support symbol references for DW_FORM_ref_addr

  1. write/unit: rework conversion of .debug_info references 

    Split the .debug_info conversion into two passes, one for entries
and one for attributes.

This allows us to convert attributes directly, instead of needing the
temporary AttributeValue::UnitSectionRef, and will also better support
.debug_info references in expressions.

  1. write: implement expressions 

    Expressions are now are Vec of operations, instead of raw bytecode.
This is required to support addresses and references within the
expression.
