`import.meta.glob` searches in `dist/`

[brillout]

Describe the bug

Similarly to #1974 (Ignore node_modules/ when running import.meta.glob), import.meta.glob searches inside dist/.

This is problematic because:

1. First $ vite build run generates files in dist/.
2. Second $ vite build run includes files inside dist/ of the previous build.
3. Third $ vite build run includes files of both the second and the first build.

This leads dist/ to grow indefinitely after each vite build. This also leads to recursively growing bundle sizes.

Simply adding config.build.outDir to fast-glob's ignore is not sufficient. For example, following builds don't know each other's config.build.outDir:

• $ vite build --ssrManifest --outDir dist/client
• $ vite build --ssr src/entry-server.js --outDir dist/server

For the same reason, removing dist/ before $ vite build isn't a solution either.

Instead, I'm proposing the more drastic but also more powerful solution #1986 - Programmatic definition of entries (alternatively to import.meta.glob).

(The rest of the bug template is not applicable.)

I don't really consider this a bug, since it matches what matches the glob. The idea is you should only use glob patterns that are specific and ideally in a nested src directory.
