refactor(frontend-canister): Asset is_aliased -> enable_aliasing

[ericswanson-dfinity]

Description

Changes the name of the Asset field is_aliased to enable_aliasing. Note that this does not affect the external interface.

This reflects the actual meaning of the field, which may be true even for assets that are not actually aliased.

The motivation is that I am writing an interface document for the asset canister, and the misnaming of this field makes parts of that more difficult. Also, while in the CreateAssetArguments the field is correctly called enable_aliasing, the is_aliased naming has already propagated to the set_asset_properties and get_asset_properties methods. Therefore a further motivation is to discourage further propagation and to consider updating those methods in a backwards-compatible way.

How Has This Been Tested?

Covered by existing tests.

Unfortunately this will/would have to deal with upgrades
