Implement BDD style aliases as separate modules

This PR implements BDD (Behavior-Driven Development) style API for MockK as proposed in issue #439. The implementation provides aliases for existing MockK functions with BDD-oriented naming

• given (alias for every)
• coGiven (alias for coEvery)
• then (alias for verify)
• coThen (alias for coVerify)

Following discussions in PR #662, these aliases are implemented as separate modules to avoid confusion and maintain code consistency.

New Modules

• mockk-bdd: Base module with BDD style aliases
• mockk-bdd-android: Android-specific module (but... just wrapping mockk-bdd 😂)
  Separate Modules: As suggested in PR [#439] Implement BDD style alias methods #662 discussion, BDD aliases are implemented as separate modules to
• Avoid confusion with existing APIs
• Allow teams to choose their preferred style
• Maintain code consistency in projects

Usage

// Regular MockK
testImplementation("io.mockk:mockk:x.y.z")

// Add BDD style
testImplementation("io.mockk:mockk-bdd:x.y.z")

// For Android
androidTestImplementation("io.mockk:mockk-bdd-android:x.y.z")

Example

// Given
given { myService.getValue() } returns "test value"

// When
val result = myService.getValue()

// Then
then { myService.getValue() }
assertEquals("test value", result)

Testing

• Added comprehensive tests for all BDD functions
• Verified compatibility with existing MockK functions
• Tested locally via publishToMavenLocal and confirmed functionality in sample project
