MyEID: simplify key component loading
MyEID: simplify key component loading

Encode the component ID to be key type and component ID. This allows
each combination to be unique and direct mapping to card component
ID type in the code by just taking the low byte. This simplifies
the code, and reduces confusion as there is now only one #define
for each component.
