feat: search by tile using tileIdentifier

[sbrunato]

Adds a new metadata and search parameter: tileIdentifier.

This standardizes the search by tile for the following providers: peps, theia, mundi, onda, creodias, cop_dataspace, planetary_computer, earth_search.
For example:

from eodag import EODataAccessGateway
dag = EODataAccessGateway()

products, _ = dag.search(
    productType="S2_MSI_L1C",
    start="2018-06-01",
    end="2018-06-15",
    tileIdentifier="31TFK"
)

assert products[0].properties["tileIdentifier"] == "31TFK"

You can check in the documentation that tileIdentifier is marked as queryable metadata for the mentioned providers.

The Search for products by tile tutorial has also been updated to include this feature.

EOProduct properties construction was updated to ignore values containing "Not Available" instead of just being equal to "Not Available" (needed for earth_search)

Resolves #671
Fixes #255
Fixes #556
