Use `Array[Integer]` and coerce these to an integer arrays.

Note that if `Array` were used with this lambda, things worked work with
Grape v1.3. However, `Array[String]` did not. Standardize everything on
using `Validations::Types::CommaSeparatedToIntegerArray.coerce` with
`Array[Integer]`

1. `Grape::API::Instance` instead of `Grape::API` is required, unless we
solve https://gitlab.com/gitlab-org/gitlab/-/issues/215230.

2. Grape parameters defined with `Array` types (e.g. `Array[String]`,
`Array[Integer]`) must have a `coerce_with` block or they will fail to
parse properly. See
https://github.com/ruby-grape/grape/blob/master/UPGRADING.md for more
details.

This brings in Ruby 2.7 suport and a number of fixes:
https://github.com/ruby-grape/grape/blob/master/CHANGELOG.md

1. Move all inherited Grape::API -> Grape::API::Instance
2. Remove use of Virtus since this has been removed from Grape.
3. Extract Rack::Response from API error
4. Grape v1.2.3 pulled in a fix used in SafeFile:
https://github.com/ruby-grape/grape/pull/1844, so we no longer need
to maintain our custom type.
5. Adapt WorkhorseFile with the latest changes to make custom types work
with Grape and dry-types.
6. Ensure Array[String] is coerced properly.

The change from Virtus to dry-types now requires all strings to be
coerced to arrays. Before this was done within Virtus.

7. Coerce Array[Integer] types to arrays of integers

The change from Virtus to dry-types now requires all strings to be
coerced to arrays of integers. Before this was done within Virtus.
