in_winevtlog: Handle Daylight saving time by using newer functions

[cosmo0920]

• SystemTimeToTzSpecificLocalTimeEx
• GetDynamicTimeZoneInformation

are able to handle Daylight Saving Time(DST).

FileTimeToLocalFileTime and SystemTimeToTzSpecificLocalTimeEx
automatically convert between ST and DST.
These functions are working well for DST conversions.

Then, we got:

[663] winevtlog.0: [[1753251022.125331400, {}], {"ProviderName"=>"Microsoft-Windows-RestartManager", "ProviderGuid"=>"{0888E5EF-9B98-4695-979D-E92CE4247224}", "Qualifiers"=>"", "EventID"=>10001, "Version"=>0, "Level"=>4, "Task"=>0, "Opcode"=>0, "Keywords"=>"0x8000000000000000", "TimeCreated"=>"2025-05-10 05:13:42 -0700", "EventRecordID"=>3959, "ActivityID"=>"", "RelatedActivityID"=>"", "ProcessID"=>34096, "ThreadID"=>61344, "Channel"=>"Application", "Computer"=>"hiro-area51-14", "UserID"=>"NT AUTHORITY\SYSTEM", "Message"=>"Ending session 0 started ΓÇÄ2025ΓÇÄ-ΓÇÄ05ΓÇÄ-ΓÇÄ10T12:13:42.448394200Z.", "StringInserts"=>[0, "2025-05-10 05:13:42 -0700"]}]
[664] winevtlog.0: [[1753251022.125822100, {}], {"ProviderName"=>"Microsoft-Windows-RestartManager", "ProviderGuid"=>"{0888E5EF-9B98-4695-979D-E92CE4247224}", "Qualifiers"=>"", "EventID"=>10000, "Version"=>0, "Level"=>4, "Task"=>0, "Opcode"=>0, "Keywords"=>"0x8000000000000000", "TimeCreated"=>"2025-05-10 05:13:42 -0700", "EventRecordID"=>3960, "ActivityID"=>"", "RelatedActivityID"=>"", "ProcessID"=>34096, "ThreadID"=>61344, "Channel"=>"Application", "Computer"=>"hiro-area51-14", "UserID"=>"NT AUTHORITY\SYSTEM", "Message"=>"Starting session 0 - ΓÇÄ2025ΓÇÄ-ΓÇÄ05ΓÇÄ-ΓÇÄ10T12:13:42.785623300Z.", "StringInserts"=>[0, "2025-05-10 05:13:42 -0700"]}]

PST is now under Daylight Saving Time(DST).
So, it's correct behavior for the DST implemented timezone.

This was originally reported in #8386.
