Avoid allocations in Utf8Formatter.TryFormat(float/double, ...) (#22011)
* Avoid allocations in Utf8Formatter.TryFormat(float/double, ...)
Currently every call to Utf8Formatter.TryFormat for a float or a double allocates two strings, one for the format string and one for the resulting number. This avoids those in the common case where we can use float/double.TryFormat and format directly into a stack buffer. Also removes some unsafe code; the performance of StandardFormat.ToString isn't currently worth the extra nanoseconds gained by using unsafe code.
* Delete assert
There's a test that uses unsafe code to cause this to fail and validate that no exception is thrown.
