Original change's description:
> Port net::CookieCryptoDelegate to os_crypt async
>
> This change replaces usage of OSCrypt::{Encrypt,Decrypt}String in
> cookie_store_util.cc with async equivalents, so CookieCryptoDelegate now
> takes a OSCryptAsync which must be plumbed through everywhere it's used,
> which was in 2 places:
>
> 1. services/network/network_context.cc
>   - This runs out of the browser process, so no OSCryptAsync is
>     available.  GetCookieCryptoDelegate was only created when a
>     cookie_encryption_provider was not provided, but since M122,
>     UseOsCryptAsyncForCookieEncryption was enabled by default (and
>     the flag has since been removed), so a cookie_encryption_provider
>     is always provided, so the GetCookieCryptoDelegate codepath is
>     removed.
>   - The exception to cookie_encryption_provider always being provided
>     is headless, which must now initialize OSCryptAsync.
>     - cookie_encryption_provider_impl.h is moved to a common location
>       so that it may be shared with headless.
>     - As of PS17, android_webview now also uses
>       CookieEncryptionProviderImpl since it also needs to provide a
>       cookie crypto delegate.
> 2. chrome/browser/extensions/chrome_extension_cookies.cc
>   - g_browser_process->os_crypt_async() is now plumbed in.
