Show object count next to each sync type

Description

Google can display the count for each object type for your sync chain if you visit https://chrome.google.com/sync. You can’t do anything with this information- but it does let you see the count.

Here’s how it looks:

We could potentially show this same type of data in Brave on brave://sync; specifically where the different types are toggled:

We could show the current counts to the right (how many on server, how many on client). If a limit is reached, we could show a red warning label, something like: “Error! Your history object count has exceeded the maximum allowed! Only your most recent history is synced” (or similar). This could be shown next to the type or at the top of the screen.

When the user sees these counts, they might want to then turn off that particular sync type. Especially if it's causing them to hit a limit.

NOTE: this follow up is a longer term client-side fix for the server-side changes made in #35042

We can split this issue into platform separate issues when if we're ready to do this (have mock ups, it's prioritized, etc).

A follow up for this issue could be offering a way for the user to put in a request to delete all records for a given record type (ex: History). This would have let users who hit the bad state in #35042 get back into a good state. If the user was able to delete all history entries (what was taking up the quota), it could have got them back working again.
