fix(store): restore bytesN helpers

[holic]

These were removed in #2090 as part of audit fixes because they appeared unused, but we missed that they are used by codegen (likely because the function signature is generated by a template string):

mud/packages/store/ts/codegen/field.ts

Line 269 in 1a82c27

const innerSlice = `Bytes.slice${staticByteLength}(_blob, ${offset})`;

Shoutout to @transmissions11 for spotting this and kicking this off in #2402

While I was here, I renamed the helpers from Bytes.sliceN to Bytes.getBytesN to both match the Bytes.setBytesN methods and to better differentiate this from Slice and SliceLib utils.

Great spot! I wish there was a way we could not get the compiler warning
