Change kernel procedures from export to proc

[Fumuran]

What should be done?

As soon as we will be able to compile a "dead code" (as it was described in this comment), we should change the type of the kernel procedures from export to proc. This change should be done for all procedures, except for exec_kernel_proc one, because all these procedures will be called only by dynexec instructions in the exec_kernel_proc.

How should it be done?

Types of the dynamically executed kernel procedures in the api.masm file should be changed from export to proc.
If the hashes of these procedures will change, they also should be updated in the procedures.rs file.

When is this task done?

This task is done when dynamically executed kernel procedures, which are described as proc procedures, could be executed by their hash using exec_kernel_proc procedure.
