[WIP] Address review comment from gemini-code-assist

[Copilot]

Plan to Address gemini-code-assist Review Comment

The review comment from PR #3118 suggests simplifying a LINQ expression in ReflectionCache.cs:

Current pattern (less efficient):

.Select(prop => new { Property = prop, Attribute = prop.GetCustomAttribute<RequestParameterAttribute>(inherit: false) })
.Where(x => x.Attribute != null)
.Select(x => new PropertyWithAttribute(x.Property, x.Attribute))

Suggested pattern (more efficient):

.Select(prop => new PropertyWithAttribute(prop, prop.GetCustomAttribute<RequestParameterAttribute>(inherit: false)))
.Where(pwa => pwa.Attribute != null)

Tasks:

• Understand the review comment
• Create a demonstration file showing both patterns
• Document the improvement (avoiding intermediate anonymous type allocation)
• Add example code that can be referenced for the actual PR
• Verify the code compiles and demonstrates the pattern correctly

Original prompt

Can you address the single review comment from gemini-code-assist under googleapis/google-api-dotnet-client#3118 or suggest what should I do?
