Currently we convert objects to strings using `'' + value` which is quickest, but it stringifies the value using its `valueOf`, rather than `toString`. These changes switch to using `String(value)` which has identical performance and calls the `toString` method as expected. Note that another option was calling `toString` directly, but benchmarking showed it to be slower. I've included the benchmark I used to verify the performance so we have it for future reference and we can reuse it when making changes to `renderStringify` in the future. Also for reference, here are the results of the benchmark: ``` Benchmark: renderStringify concat: 2.006 ns(0%) concat with toString: 2.201 ns(-10%) toString: 237.494 ns(-11741%) toString with toString: 121.072 ns(-5937%) constructor: 2.201 ns(-10%) constructor with toString: 2.201 ns(-10%) toString mono: 14.536 ns(-625%) toString with toString mono: 9.757 ns(-386%) ``` Fixes #38839. PR Close #39843
