* Add DirectoryFilterPattern parameter to regeneration pipeline

Add DirectoryFilterPattern parameter to archetype-typespec-emitter.yml
and New-RegenerateMatrix.ps1 to allow filtering the regeneration matrix
by package directory name pattern.

This enables azure-sdk-for-net's http-client-csharp-mgmt CI to only
regenerate Azure.ResourceManager* SDKs instead of all TypeSpec SDKs.

* Handle empty filter results with array wrapping and early error

Address review feedback: wrap filtered results in @() to ensure
reliable .Count, and fail fast with a clear error when no directories
match the filter pattern.

* Support comma-separated filter patterns

Update DirectoryFilterPattern to split on commas and match any pattern,
so callers can filter to multiple SDK prefixes (e.g.,
'Azure.ResourceManager*,Azure.Provisioning*').
