V10 - Reduce usage of temp AspNetCoreHostingEnvironment (#12270)

* Move MapPathWebRoot & MapPathContentRoot to extension methods.

* Set AspNetCoreHostingEnvironment ApplicationId without service provider.

* Drop some usages of TempHostingEnvironment

* Logging setup cleanup - AppDomainId has no value (it is always "1")

Creating new AppDomains isn't possible in .Net core.
Attempting to do so results in a platform exception.

A dotnet core process has a single AppDomain instance whose Id property
is always the integer 1.

* Setup logging without IHostingEnvironment

* Mark IUmbracoBuilder.BuilderHostingEnvironment obsolete
And remove internal usages.

* Typeloader no longer uses umbraco-types.list

* Added UmbracoHost - setup serilog two-stage init.

* Add ApplicationIdEnricher

* Defensive tweaks for those not using UmbracoHost

* Drop UmbracoHost static class

* Setup runtime logger without host builder extensions.

* Prevent RefreshingRazorViewEngine related explosions

* Filescoped namespaces for new classes.

* Apply suggestions from code review
