Performance: Add an index to Change cmLocalGenerator::GeneratorTargets.

Browse Source 
Add an index to Change cmLocalGenerator::GeneratorTargets for faster lookup by
name.

Also changed a bunch of uses of cmLocalGenerator::GetGeneratorTargets() to take
const references instead of copying the vector.

Represent generator targets as a map (name -> target) to make name lookups more
efficient instead of looping through the entire vector to find the desired one.
