Update embedded-services + hals

[kurtjd]

Recently updated uart-service to use v7 of embedded-io-async so update embedded-services here to pull in those changes. Additionally had to make several changes to all the HALs (embassy-imxrt, embassy-mcxa, embassy-npcx, and embassy-qemu-riscv) to clean some things up (like updating those hals to impl v7 and implementing the traits for unsplit uart instances).

This allows some cleanup here such as removing all the uart wrappers.

If the unvetted dependencies are needed

Post a new comment with the questionnaire below to the PR to help the auditors vet the dependencies.
After the auditors have vetted the dependencies, the PR will need to be rebased to pick up the new audits and pass this check.

Copy and paste the questionnaire as a new comment and provide your answers:

1. What crates (with version) need to be audited?

2. How many of the crates are version updates vs new dependencies?

3. To confirm none of the already included crates serve your needs, please provide a brief description of the purpose of the new crates.

4. Any extra notes to the auditors to help with their audits.

Pull request overview

This PR updates the firmware’s OpenDevicePartnership embedded-services dependency set (including uart-service moving to embedded-io-async v0.7) and aligns platform HAL usage to remove now-unnecessary UART adapter/wrapper layers.

Changes:

• Bump platform-common to explicitly include embedded-io/embedded-io-async v0.7 to match the updated service stack.
• Update dev-npcx and dev-mcxa to pass HAL UART instances directly into uart-service tasks (removing wrapper/adapter code).
• Refresh per-platform lockfiles to the new embedded-services + HAL revisions.
