refactor(solid): remove preset and simplify `tsup` configuration

[moonlitgrace]

Description

simplified tsup.config.ts config by removing tsup-preset-solid and utilizing esbuild-plugin-solid directly. only modified default values of tsup config. separate version of extended tsconfig.build.json for tsup build.

writing package.json on build step is not a necessary thing like tsup-preset-solid does.

✅ Tested with dotlottie-solid-example
