[PM-9035] desktop build logic to provide credentials to os on sync (#10181)

* feat: scaffold desktop_objc

* feat: rename fido2 to autofill

* feat: scaffold electron autofill

* feat: auto call hello world on init

* feat: scaffold call to basic objc function

* feat: simple log that checks if autofill is enabled

* feat: adding some availability guards

* feat: scaffold services and allow calls from inspector

* feat: create custom type for returning strings across rust/objc boundary

* chore: clean up comments

* feat: enable ARC

* feat: add util function `c_string_to_nsstring`

* chore: refactor and rename to `run_command`

* feat: add try-catch around command execution

* feat: properly implement command calling

Add static typing. Add proper error handling.

* feat: add autoreleasepool to avoid memory leaks

* chore: change objc names to camelCase

* fix: error returning

* feat: extract some helper functions into utils class

* feat: scaffold status command

* feat: implement status command

* feat: implement password credential mapping

* wip: implement sync command

This crashes because we are not properly handling the fact that `saveCredentialIdentities` uses callbacks, resulting in a race condition where we try to access a variable (result) that has already gotten dealloc'd.

* feat: first version of callback

* feat: make run_command async

* feat: functioning callback returns

* chore: refactor to make objc code easier to read and use

* feat: refactor everything to use new callback return method

* feat: re-implement status command with callback

* fix: warning about CommandContext not being FFI-safe

* feat: implement sync command using callbacks

* feat: implement manual password credential sync

* feat: add auto syncing

* docs: add todo

* feat: add support for passkeys

* chore: move desktop autofill service to init service

* feat: auto-add all .m files to builder

* fix: native build on unix and windows

* fix: unused compiler warnings

* fix: napi type exports

* feat: add corresponding dist command

* feat: comment signing profile until we fix signing

* fix: build breaking on non-macOS platforms

* chore: cargo lock update

* chore: revert accidental version change

* feat: put sync behind feature flag

* chore: put files in autofill folder

* fix: obj-c code not recompiling on changes

* feat: add `namespace` to commands

* fix: linting complaining about flag

* feat: add autofill as owner of their objc code

* chore: make autofill owner of run_command in core crate

* fix: re-add napi annotation

* fix: remove dev bypass
