[vm/bytecode] Fix AST removal for package-split kernel files with bytecode

In package-split mode, bytecode generation is performed separately for
each package. Previously, dropping AST was done right after generating
bytecode. However, dropping AST for a package makes it impossible to do
constant evaluation in other packages which import the package with dropped
AST. This breaks bytecode generation for subsequent packages.

To work around this problem, in package-split mode AST is removed
temporary until dillp file is written. After that, removed AST is restored
back.
