fix(optimizer): align relative `build.rollupOptions.input` resolution with rollup

[sapphi-red]

Description

computeEntries resolves relative build.rollupOptions.input from the root. https://github.com/vitejs/vite/blob/61b6b96b191c6071b9c574ad4c795f97f2646f18/packages/vite/src/node/optimizer/scan.ts#L244-L265 https://github.com/vitejs/vite/blob/61b6b96b191c6071b9c574ad4c795f97f2646f18/packages/vite/src/node/server/pluginContainer.ts#L341-L344 reproduction: https://stackblitz.com/edit/vitejs-vite-nte18shp?file=package.json,vite.config.js&terminal=dev

On the other hand, rollup resolves relative build.rollupOptions.input from process.cwd().

This PR fixes the computeEntries to align the behavior with rollup. I think we should align with rollup, but that would probably have a bigger impact, so I made that a separate PR.

A workaround is to call path.resolve in the config before passing to build.rollupOptions.input.

Hmm, it seems vike fails on this branch and passes on latest main (https://github.com/vitejs/vite-ecosystem-ci/actions/runs/151765559389). The error is happening in build, which is strange...

[sapphi-red]

It seems pnpm tsx ecosystem-ci.ts vike --repo sapphi-red/vite --branch fix/optimizer-resolve-relative-build-rollupOptions-input passes, but pnpm tsx ecosystem-ci.ts vike --repo sapphi-red/vite --commit 7872cfc6181bd19fe6f42d8990a0ddfa56dbf8f8 fails.

[sapphi-red]

It seems it passes with rollup 4.38.0 and fails with 4.39.0.

[sapphi-red]

OK. pnpm tsx ecosystem-ci.ts vike --repo sapphi-red/vite --branch fix/optimizer-resolve-relative-build-rollupOptions-input sets overrides.rollup: '4.40.1' and pnpm tsx ecosystem-ci.ts vike --repo sapphi-red/vite --commit 7872cfc6181bd19fe6f42d8990a0ddfa56dbf8f8 sets overrides.rollup: '^4.40.0' (because it uses pkg.pr.new), and there was a bug in rollup 4.39.0 - 4.40.0. So the failure is not caused by this PR.

vike is failing with a different error but the reason is same with https://github.com/vitejs/vite/pull/20080#issuecomment-2899825610 and not caused by this PR.
