Remove interpreter instance manager from pvm-host-calls and depend only on pvm-interface

[coderabbitai]

Context

As discussed in PR #716, the pvm-host-calls package currently depends on @typeberry/pvm-interpreter and @typeberry/pvm-interpreter-ananas because of the interpreter instance manager.

Ideally, this package should only depend on @typeberry/pvm-interface and not any specific interpreter implementations.

Objective

• Remove the interpreter instance manager from pvm-host-calls
• Refactor the package to only rely on @typeberry/pvm-interface
• Eliminate dependencies on @typeberry/pvm-interpreter and @typeberry/pvm-interpreter-ananas
