Fixing mockery infinitely generating its own interfaces

[LandonTClipp]

Description

Mockery currently will generate mocks for the interfaces it creates in its own auto-generated files. This is fixed by making the interface in-line in the function signature, which causes mockery to not attempt generating a mock for it.

• Fixes Mockery generates mocks of auto-generated code when mocks are generated in-package. #632
• Removing string comparison tests. These are not useful and are extremely burdensome when making changes to the mock generation code.
• Regenerating mocks using new mock generation logic.

TODO

Create integration test that asserts the number of files in the project over multiple mockery runs does not change.

Type of change

• Bug fix (non-breaking change which fixes an issue)
• New feature (non-breaking change which adds functionality)
• Breaking change (fix or feature that would cause existing functionality to not work as expected)
• This change requires a documentation update

Version of Golang used when building/testing:

• 1.11
• 1.12
• 1.13
• 1.14
• 1.15
• 1.16
• 1.17
• 1.18
• 1.19
• 1.20

How Has This Been Tested?

Added a new fixture and config in mockery to test the "in-package recursive" behavior. It was confirmed manually that mockery no longer generates mocks for its own interfaces.
