Customer Security PreTrimmer needs Updating for SharePoint 2019

[Seferan]

Guidance needs to be updated for SharePoint 2019. Microsoft.Office.Server.Search.Query is now compiled using .NET Framework 4.8 which utilizes WIF from System.Security.Claims instead of Microsoft.IdentityModel.Claims. Minimal changes are required for PreTrimmer:

• Reference System.Security.Claims instead of Microsoft.IdentityModel.Claims
• Change References from IClaimIdentity to ClaimsIdentity
• Change claim.ClaimType to claim.Type
