Enable AOT for dotnet-monitor

[sbomer]

This issue tracks the work remaining to make dotnet-monitor AOT-compatible. Note this doesn't track the deployment work required to actually ship an AOT version.

• Replace reflection-based options mapping logic
  [feature/10.0] Replace reflection-based options mapping logic #8233
• Replace reflection-based options validation
  [feature/10.0][WIP] Use options validation source generator #8254
• Fix errors when using RequestDelegateGenerator
  Error in RequestDelegateGenerator generated code (assigns int to enum) aspnetcore#62910
• Work around Trim warnings for MinLengthAttribute runtime#112111
  These warnings can be suppressed once using AOT-compatible validation
• Replace remaining calls to Validator.ValidateObject using AOT-compatible validation
• Add trim annotations to ServiceCollectionExtensions
• Turn on STJ source generator

Follow-up items (not necessary for AOT but should be completed when possible):

• [feature/10.0] Remove checked-in configuration binding generated sources #8208
