QueryRunner.dropColumns doesnt accept list of column names as strings

[mateusppereira]

Feature Description

Add support to an array of strings on dropColumns method.

The Problem

The current version of QueryRunner.dropColumns method only supports a list of TableColumns and it makes the code more verbosity and less consistent.

The Solution

The solutions was easy, since the dropColumn method already accept a string as column name.

For an specific driver I was forced to check if it was already an instance of TableColumn and, if not, I find the column on table.

Considered Alternatives

Additional Context

before:

await queryRunner.dropColumns(
  'table_x',
  [
    new TableColumn({ name: 'id', type: 'int' }),
    new TableColumn({ name: 'name', type: 'varchar' }),
  ],
)

after:

await queryRunner.dropColumns('table_x', ['id', 'name'])
