Some refactorings to improve wildcard performance on debug CTS builds

Some refactorings to improve wildcard performance on debug CTS builds

Measuring a VS2019 debug build running "--deqp-case=dEQP-VK.*faketestname" these changes
take the runtime from 800 seconds to 240 seconds

Tests run locally:

 --deqp-case=dEQP-VK.*faketestname and confirmed zero tests run and improved performance with debug build

Following commands run and confirmed same count of tests before and after the change:

Wildcard without dot

 --deqp-case=dEQP-VK.ray_tracing_pipeline*rgen*

Wildcard with dot

 --deqp-case=dEQP-VK.info.*

Wildcard at start and end

 --deqp-case=*peer_memory*
