CSP Violation when `unsafe-eval` is not set

[dgautsch]

Reporting a bug?

For sites that have a CSP and do not inlcude unsafe-eval The i18n compilation file breaks due to this line:

https://github.com/intlify/vue-i18n-next/blob/8fd6a1b5fdacba7024ce260250a6d289032036cc/packages/core-base/src/compilation.ts#L94

core-base.mjs:942 Uncaught (in promise) EvalError: Refused to evaluate a string as JavaScript because 'unsafe-eval' is not an allowed source of script in the following Content Security Policy directive: "script-src 'self' 'nonce-doNVvddpMzAmzhAPA2NgiyY69SiU88Xx' 'strict-dynamic' https:".

    at wrapWithDeps (vue-i18n.mjs:551:1)
    at Object.t (vue-i18n.mjs:564:1)

Expected behavior

The site should be able to run the i18n library without needing to add unsafe-eval to the Content Security Policy

Reproduction

I'd recreate in stackblitz but I can't set custom security policies.
