[0.6.x] Do not inline small assets, by default

[timacdonald]

By default Vite will "inline" assets that are smaller than 4kb by base64 encoding them.

From a Laravel perspective this can cause issues for Blade apps that are looking to use the Vite::asset() helper on small assets.

Blade specific apps could set this to 0 manually, however I also find the inconsistent behaviour as the default strange - even if it is beneficial to SPA style applications. I feel setting this to 0 is a good default for Laravel, while still respecting the user configured value.

The alternative would be to add some magic into the asset helper, but I don't think we can generally assume the file will still be in it's pre-bundled location (e.g. resources/images/pixel.png) as apps may clear that stuff out for space reasons (e.g. Serverless).

Encoding at runtime also kinda sucks as well - and the inconsistency in the returned result is a little weird (plain URL vs base64 url).

I think if this is something the community wants we could add an additional function assetOrEncoded() or something along those lines. But I think we can punt that down the road for now.

Looks good. I'm curious why 0.6.0 though?

[timacdonald]

As it will change existing functionality from under the user, i.e. 4kb assets will now be in the build dir.

I'm happy to see it as a feature rather than a breaking if you think that would be better.

I see it as a bug fix for a new Laravel feature

Sounds good to me. We bumped to 6.0 with the last release so I can just leave this as is now.
