Reland "[pkg/native_stack_traces] Support Mach-O dSYM debugging information."
This is a reland of commit 08c13f173c
Fixes test failures on non-x64 architectures, both in the test
harness and due to DWARF5 line number program headers having a
non-backwards compatible format. (We generate DWARF2 in the
ELF snapshot writer, but the assembler used for assembly snapshots
may generate DWARF5.)

## 0.5.0
|
||||
|
||||
- Require Dart >= 2.17 (enhanced enum support)
|
||||
- Add support for parsing DWARF in Mach-O files and dSYM directories.
|
||||
- Add some support for DWARF5.
|
||||
- Add `dump` command to replace the old `--dump_debug_file_contents`
|
||||
flag to `find` and `translate`.
|
||||
|
||||
## 0.4.6
|
||||
|
||||
- Upgrade to `package:lints` 2.0.
