  [JSC] Use simdutf for fromBase64

Reviewed by Yijia Huang.

This patch integrates simdutf into fromBase64.

1. When "strict" or "stop-before-partial" options are specified, we use fallback implementation[1]. Once they are implemented, we will switch to that.
2. Upgrade simdutf to fix issues found during implementing TC39 Base64 features.
