feat(collector): adds spec.hostPID for all collector modes

[olandr]

Description: At the moment it is not possible to set the spec.hostPID field for the collector (regardless of type). This change adds a featuregate operator.security.hostpid that allows a user to configure the spec.hostPID field for the collector.

Inspiration for the code follows from the functionality of the hostNetwork boolean field Link to tracking Issue(s): 4214

• Resolves: #4214

Testing: <Describe what testing was performed and which tests were added.>

• adds e2e tests for all types
• adds unit tests for configuring the hostPID depending on featureflag activation.

Documentation: <Describe the documentation added.> Autogenerated docs from the type defs.
