Add field:base-info command

[DieterHolvoet]

This PR adds a command to show information about base fields, similar to #4928. It has already been used in multiple projects as part of the wmscaffold module and is in my opinion stable enough to be considered to be merged in Drush.

Remarks

• AskBundleTrait and ValidateEntityTypeTrait are also included in Add field:delete command #4926, Add field:info command #4928 and Add field:base-override-create command #4929.
• FieldDefinitionRowsOfFieldsTrait is also included in Add field:info command #4928.

Test scenarios

• ./vendor/bin/drush bfi => Not enough arguments (missing: "entityType").
• ./vendor/bin/drush bfi node => Lists the default columns
• ./vendor/bin/drush bfi node --fields=field_name,field_type => Lists only the field name and field type columns

TODO

• Add tests

[weitzman]

• Needs some updating as AskBundleTrait no longer exists
• Lets keep using field as the command namespace IMO. So field:info-base (or field:base-info to go along with field:base-override).
• I will finish tests once above are done.
• One all field commands are in, lets move them and the traits to a new Drupal\Commands\field namespace. They are currently in Drupal\Commands\Core

I did the changes.
