Migrated from robin_hood to unordered_dense (for UnorderedMap and UnorederedSet).

Added support for SmallVector using svector (and we are already using it in a couple of places).
Added debug symbol inspector script for the new SmallVector in project/scripts/debug.
Added tilde support for files and folders passed as parameters from the CLI in ecode (and added FileSystem::expandTilde).
Fixed a bug in "light-dark" parsing.
