Correct crate version numbers that have broken semver

The semver CI check is great but only checks the immediate crate in
question. It doesn't catch that many of our crates depend on
`lightning` and thus have actually broken semver as the types they
use have changed to `lightning` 0.3.

Here we hump the version of crates that have actually changed
semver since 0.2.

In addition to those that depend on `lightning`,
`lightning-invoice`'s API has changed (but was not being checked by
the semver CI task).

Finally, `lightning-macros` was updated to 0.2.1, so the version is
changed to 0.2.2.

The short version

What changed, and why it matters

This commit only changes version numbers in package configuration files (Cargo.toml). It bumps crate versions from 0.2.x to 0.3.x to keep them aligned with semantic versioning rules after the underlying `lightning` crate changed its public types. There is no code change, no bug fix, and no security patch.

Recommended action

No security action required. Treat as a normal release-engineering/versioning change.

Security signals we found

No strong security signals were identified.

Technical analysis

Evidence from the diff

The diff updates version fields and dependency version requirements across ten Cargo.toml files in the rust-lightning workspace. The stated purpose is to correct broken semver declarations: downstream crates expose lightning 0.3 types in their APIs, so they must be versioned 0.3.x themselves. lightning-invoice is bumped to 0.35.0 because its own API changed, and lightning-macros moves to 0.2.2 to follow a prior 0.2.1 release. No Rust source code, build logic, or cryptographic behavior is modified.
