perf: prefer NewFromUtf8Literal() over NewFromUtf8() for string literals (#44412)

Browse source 
* perf: prefer NewFromUtf8Literal() over NewFromUtf8() for string literals

the string length is known at compile time and no need to call ToLocalChecked()

* perf: string length is known when calling NewFromUtf8(), so use it

* perf: remove unnecessary calls to c_str()

these just force the code being called to have to recalculate the string length
