Remove duplicate AZC0012 analyzer

[Copilot]

AZC0012 (single-word type name detection) is now implemented in the new analyzer package. This removes the duplicate implementation from Azure.ClientSdk.Analyzers only.

Changes

Removed from Azure.ClientSdk.Analyzers:

• TypeNameAnalyzer.cs - AZC0012 implementation
• AZC0012 descriptor from Descriptors.cs
• AZC0012Tests.cs - all test cases

No changes to other files:

• ErrorAnalyzers package remains unchanged (prompts, tests, samples all retain AZC0012 support)
• Documentation references to AZC0012 remain unchanged
• test-proxy NoWarn list remains unchanged (still includes AZC0012)

Preserved:

• NamingSuggestionHelper.cs - used by multiple analyzers (AZC0034, AZC0030, AZC0031, AZC0032, AZC0033, AZC0036)
• All AZC0012 references outside of Azure.ClientSdk.Analyzers - error code continues to exist from new package

If you need me to access, download, or install something from one of these locations, you can either:

• Configure Actions setup steps to set up my environment, which run before the firewall is enabled
• Add the appropriate URLs or hosts to the custom allowlist in this repository's Copilot coding agent settings (admins only)
