fix(brillig_gen): Pass correct size of complex types input for brillig foreign calls

[vezenovm]

Description

We were passing the size of an array from Type::Array directly when generating the inputs for a brillig foreign call. This wouldn't break for normal arrays or singular structs, but breaks in the case of an array of structs. For example if we have an array of two structs with two fields each, only the first two fields would be passed to the foreign call as the entire array is of size 2.

Additional Context

PR Checklist*

• I have tested the changes locally.
  I held off on adding a struct test directly as my println PR will have much more comprehensive tests that deserialize arrays of structs.

• I have formatted the changes with Prettier and/or cargo fmt on default settings.
