Aaron Klotz	8cdfd12977	net/dns: update Windows split DNS settings to work alongside other NRPT entries set by group policy. ... When there are group policy entries for the NRPT that do not belong to Tailscale, we recognize that we need to add ourselves to group policy and use that registry key instead of the local one. We also refresh the group policy settings as necessary to ensure that our changes take effect immediately.

Aaron Klotz	b005b79236	net/dns, paths, util/winutil: change net/dns/windowsManager NRPT management to support more than 50 domains. ... AFAICT this isn't documented on MSDN, but based on the issue referenced below, NRPT rules are not working when a rule specifies > 50 domains. This patch modifies our NRPT rule generator to split the list of domains into chunks as necessary, and write a separate rule for each chunk. For compatibility reasons, we continue to use the hard-coded rule ID, but as additional rules are required, we generate new GUIDs. Those GUIDs are stored under the Tailscale registry path so that we know which rules are ours. I made some changes to winutils to add additional helper functions in support of both the code and its test: I added additional registry accessors, and also moved some token accessors from paths to util/winutil.
