[Feature] Search for a location or metadata in smart search instead of specifically using the filters

[SerAlbi]

It would be useful and google's photo-like to have the smart search bar respond to both metadata and ai context tags.
As an example in google photo I would often search for a specific city or place and all the photos taken at that place would show up.

In immich instead we have to search with the metadata tag m:city or select the city from a dropdown of existing cities which is not very user friendly.
At least there should be an option to directly write the city you want to search instead of selecting it from a drop-down.

The same should apply to every metadata, as an example if i search for "mom" immich should show me photos of my mom instead of requiring me to select "mom" from the specific 'People' filter pill.
