DateTimeTimeZoneExtensions should respect the TimeZone Kind

[Mrnikbobjeff]

Describe the bug

In DateTimeZoneExtensions.cs, the Method ToDateTimeOffset does not respect the Timezone identifier. The method needs to add DateTimeStyles.RoundTrip to the DateTime.ParseExact invocation. A reproducable example is published here. To reproduce this the user has to be outside of the UTC Timezone.

Expected behavior

The DateTime Timezone should be respected (Z specifier for ZULU time at the end of the datetime string)

How to reproduce

Create a utc time, use it to create a DateTimeTimeZone, convert it to a DateTimeOffset when your local system is not UTC time
