Update Bazel workspace dependencies to 7.6.2 compatibility with MODULE.bazel support

Thanks for the PR! LGTM, but we will need @PiotrSikora 's review and approval as the owner.

The msrv workflow is failing due to:

error: package `quote v1.0.42` cannot be built because it requires rustc 1.68 or newer, while the currently active rustc version is 1.65.0

Seems we could either revert the quote version bump in this PR, or else change the rust.yml workflow to use a more recent Rust toolchain. @PiotrSikora WDYT?

Let's rollback cargo versions modification and focus on Bazel MODULE support

[PiotrSikora]

Could those be moved to proxy_wasm_rust_sdk_dependencies()? Otherwise, they won't be automatically executed in the dependent projects.

[PiotrSikora]

There is also a question whether we want to support the old WORKSPACE-based model. If we do, then I think we should add it to the CI to make sure it works.

[mmorel-35]

I believe it's better to start by updating dependencies and then provide the MODULE.bazel. I opened #334

You probably want to support MODULE and WORKSPACE for some few minor versions to allow the users of your library to migrate smoothly

[PiotrSikora]

Thanks for cleaning this up!

But it's now clear that this should be 2 PRs: updating rules_cc, and adding support for MODULE.bazel (unless they are somehow intertwined, but it doesn't look like it).

Could you split them? Thank you!

Why update to 7.6.2 and not the latest 7.x (i.e. 7.7.1) or even 8.x?

[mmorel-35]

7.7.1 was published only few days ago. My long term goal is to turn envoy in bzlmod and it is yet in 7.6.2 so I just need to ensure actual compatibility
