* Initial pass at optimizing product path dependency resolution

Signed-off-by: amzn-mike <80125227+amzn-mike@users.noreply.github.com>

* Add version of StripAssetPlatform that doesn't allocate or copy strings.  Re-add missing test and fix up compile errors.  Add benchmark test

* Add test for same filename on multiple platforms

Signed-off-by: amzn-mike <80125227+amzn-mike@users.noreply.github.com>

* Rework search logic to keep track of the source of a search path (source vs product) and keep track of which search matches which dependency to avoid doing another search through every product later on
