fix: do not append browserHash on optimized deps during build

[lsdsjy]

Description

Do not append browserHash on optmized deps during build. It is unnecessary and on some occasions would cause duplicate files bundled. For example, if we have multiple entries, vite will "discover and optimize new deps" and re-compute the browserHash, so it could end up with both .vite/deps_build-dist/chunk-ABCDEFGH.js?v=11111111 and .vite/deps_build-dist/chunk-ABCDEFGH.js?v=22222222 in the final bundles. They have the same content but different ids, so rollup treats them as different modules.

In fact, "entry" optmized deps have no browserHash suffix currently. Only chunks imported by "entry" optimized deps have that. For example, .vite/deps_build-dist/vue-demi.js imports vite/deps_build-dist/chunk-ABCDEFGH.js?v=11111111 and .vite/deps_build-dist/vue.js imports .vite/deps_build-dist/chunk-ABCDEFGH.js?v=22222222.

I think this happens when the user cannot correctly configure the entries for deps optimization, which is possible for complicated and highly customized projects.

Thanks for the PR! This sounds good to me, but the issue that prompted you to create this fix does not. Even if you have multiple entries, there should be a single build process and all deps must be found before optimizing. There shouldn't be any new deps discovered during build. Would you create a minimal reproduction and a bug report?

[lsdsjy]

You're right but I'm having some trouble with creating a minimal reproduction. I'll file an issue if I'd make it!

I found that it cannot be reproduced on newer vite versions. The last version where I can reproduce the "chunks with different hash" behavior is 4.2.3 and the first version that cannot reproduce is 4.3.3. However I cannot find the specific version that fixes this because my project cannot build on vite >= 4.3.0 <= 4.3.2 (it throws error in vite:optimized-deps-build). I guess it's related to some commits about deps optimizer in 4.3.0.
