feat(analyzer): add rules regarding model name suffixes

[archerzz]

• add four rules checking the suffixes of model names
• upgrade Roslyn to latest version since new rules require some API
• minor refactor existing codes
• add test cases for the new rules

resolve #6905

Should this link to our guidelines that specify the naming rules we are enforcing here?

[archerzz]

I could not find the official guidelines. We do have a OneNote page on that. @m-nash Shall we update the .NET Azure SDK Design Guidelines?

[archerzz]

Or we can do something like StyleCop.

• For each diagnostic ID, we create a page, like https://github.com/DotNetAnalyzers/StyleCopAnalyzers/blob/master/documentation/SA0001.md
• In each page, we provide explanation of the diagnostic, and provide mitigation solution.

@christothes @m-nash Changes after last review:

• replace virtual unimplemented methods with abstract methods
• performance improvement:
  • replace regular expression with string for suffix search
  • use Span to improve string manipulation performance
  • avoid extra string allocation
  • improve algorithm in several places
• relax conditions of searching model classes, now if a class contains either serialization method or a deserialization method, it's a model class. That resolves cases that model classes are not put under Models namespace.
• exclude non-public types from analysis
• fix an index out of range exception
• fix comments
• downgrade to Roslyn 4.4.0.0 which aligns with the version used in azure-sdk-for-net and fixes CS9057
• suppress AD0001, after some google search, it looks like an issue in Roslyn analyzers in version 4.4.0.0. If we chose 4.7.0.0 that problem would disappear.

CSC : warning AD0001: Analyzer 'Microsoft.CodeAnalysis.Analyzers.MetaAnalyzers.DiagnosticDescriptorCreationAnalyzer' threw an exception of type 'System.ArgumentException' with message 'Syntax node is not withi
n syntax tree'. [C:\Users\mingzhehuang\workspaces\archerzz\azure-sdk-tools\src\dotnet\Azure.ClientSdk.Analyzers\Azure.ClientSdk.Analyzers\Azure.ClientSdk.Analyzers.csproj]

Updated preview PR on azure-sdk-for-net: Azure/azure-sdk-for-net#38705

• total number of impacted SDKs has been reduced because we exclude non-public types, like https://github.com/Azure/azure-sdk-for-net/blob/8fa7955ac9cd1cf2c124f7d387ef07c2c5a53387/sdk/batch/Azure.ResourceManager.Batch/src/Generated/Models/OutboundEnvironmentEndpointCollection.cs#L14
• however, there are new SDKs impacted, because they put model classes under namespaces other than Models, which has been found due to determination logic change, like https://github.com/Azure/azure-sdk-for-net/blob/8fa7955ac9cd1cf2c124f7d387ef07c2c5a53387/sdk/anomalydetector/Azure.AI.AnomalyDetector/src/Generated/ErrorResponse.cs#L14

Changes since last review:

• replace List and Join with StringBuilder
• adopt ArrayPool to collect namespaces
• merge latest main branch
• extract analyzer descriptors to align with other analyzers

Preview PR: Azure/azure-sdk-for-net#39518 It's the same as the previous one, except that analyzer package is the latest.
