Description

Add a command to objtool that can be pointed at a masp packages and analyzes the sizes of MAST sections like nodes, basic block data, strings.

Should also have an option to produce machine readable output (e.g. json or toml) to support CI/workflow integration.

Depends on this refactor of MAST forest serialization.

Contributor guide

Research direction
Review objtool's existing commands and the MAST serialization refactor in PR #2765 to locate where section sizes are available, then add a command with optional JSON/TOML output.
