lib: unify ICU and no-ICU TextDecoder

[ChALkeR]

Better reviewed with whitespace ignored

1. Fix TextDecoder defaults to stream: true instead of false with null options #61411
2. Add support for fatal UTF-8 decoder in no-ICU version unless streaming is used
3. add utf-8 fast path to no-ICU version
4. reduce duplication of TextDecoder source
5. normalize how this[kHandle] was not set in no-ICU version
6. The refactor changes the encoding reported in the no-ICU version when encoding is recognized but unsupported: now the actual resolved encoding name is reported as unsupported when previously the original input string was reported.
   I don't think this is major, and reporting the actual encoding name is better in that case.

This will allow further fixes and common fast path for UTF-16 / fixed impl for UTF-16 as string_decoder doesn't implement UTF-16 per spec.

UTF-16 is still broken in no-ICU version here, this PR does not address that.
Tracking: #61041

There's a lazy utility in the internal utils.

@avivkeller this is not new code, it's just moved to an outer scope
Ideally all that should go away with follow-up fixes, string_decoder path is invalid anyway
I don't think it's worth refactoring it further
