Dongbo Wang a11810bf33 Improve powershell startup time (#8341 )

Major changes are as follows:
- Avoid `SecuritySupport.IsProductBinary` and unnecessary AMSI/suspicious code scan at startup time
   - Update `CompiledScriptBlockData.IsProductCode` to avoid unnecessary calls to `IsProductBinary`, which attempts to retrieve catalog signature of the target file.
   - Update `PerformSecurityChecks` to skip AMSI and suspicious code scan for the `.psd1` file that contains a safe `HashtableAst` only.
- Use customized `ReadOnlyBag` instead of `ImmutableHashSet` so that we can avoid loading the `System.Collections.Immutable.dll` completely.
- Replace `SHA1` with `CRC32` when generating module analysis cache file name
   - This remove the loading of `System.Security.Cryptography.Algorithms.dll` at startup
- Move `ConvertFrom-SddlString` to C# to remove the `Utility.psm1` file.
- Crossgen `Microsoft.ApplicationInsights.dll` and enable tiered compilation
   - Even pwsh with crossgen assemblies spends a lot time in jitting at the startup, about `191.6ms` comparing with `24.7ms` for Windows PowerShell.
   - Jitting `Microsoft.ApplicationInsights.dll` takes about `51.6ms`.
   - By crossgen `Microsoft.ApplicationInsights.dll` and enable tiered compilation, the jitting time drops to about `98.9ms`.
