Merge build options from viteConfig in compiler

[ngbrown]

I was trying to update Remix's use of @vanilla-extract/integration (which is still at v6) and came across how the new compiler package now inlines small files into the resulting CSS. These dataurl strings broke the Remix integration tests, so I figured it was better to match the prior behavior.

To match the prior behavior, I need to pass the option viteConfig.build.assetsInlineLimit: 0 into the compiler, but the build options were being ignored because the compiler is setting one of them.

So this patch is the minimum to get the option passed. I see that there have been earlier efforts to do a deep merge on the options (at least for the Vite plugin), but this is more narrow and is for the compiler.

With remix becoming react router, the upstream issue isn't really that relevant anymore, but this incidentally also fixes #1551. In #1665 I opted not to forward all the build properties as it felt a bit risky, so instead only assetsInlineLimit is propagated.

@ngbrown The fix in #1665 was released in @vanilla-extract/compiler@0.3.4.
