[JSC] add support for `Uint8Array.fromBase64` and `Uint8Array.prototype.setFromBase64`
https://bugs.webkit.org/show_bug.cgi?id=276215

Reviewed by Yusuke Suzuki.

These methods will make it easier for developers to decode typed character/byte data.

Note that there are other methods in the related proposal, but for ease of reviewing they will be implemented separately.

what size would you recommend?

base64DecodeInternal seems to use a Vector with a minCapacity of 16, but that seems to be entirely different from inlineCapacity
