DO NOT MERGE - add logins store static key manager factory

[jo]

This is for developing as logins for desktop, milestone 3. It is not intended to be merged.

1. Look at Cargo.toml, find revision for application-services, eg

interrupt-support = { git = "https://github.com/mozilla/application-services", rev = "8e84c588a5cc2686973c5026ecd240d6275d7e94" }

then rev is 8e84c588a5cc2686973c5026ecd240d6275d7e94. This branch is branched from this rev, so no need for step 2 if above rev matches.

2. Rebase jo:as-logins-on-desktop-milestone-3 (#6696) to that revision

3. replace the revision with above branch, and add logins

4. Define dependencies for uniffi

$ git diff --patch toolkit/components/uniffi-bindgen-gecko-js/components/Cargo.toml

(note 1: I haven't tested the need of declaring hawk and base16 deps with current code)
(note 2: we do not use the feature keydb because 8e84c58 did not include it yet)

5. Ensure no commits

except the Cargo dep changes

$ git status 
On branch default
Your branch is up to date with 'central/default'.

Changes not staged for commit:
  (use "git add <file>..." to update what will be committed)
  (use "git restore <file>..." to discard changes in working directory)
	modified:   Cargo.toml
	modified:   toolkit/components/uniffi-bindgen-gecko-js/components/Cargo.toml

no changes added to commit (use "git add" and/or "git commit -a")

6. Vendor Rust

$ ./mach vendor rust --force

7. Configure UniFFI exports

$ git diff --patch toolkit/components/uniffi-bindgen-gecko-js/components/lib.rs

8. Generate JavaScript Bindings

$ ./mach uniffi generate

Sadly, this currentltly fails due to https://bugzilla.mozilla.org/show_bug.cgi?id=1959469
