Problem
When the runtime desires to migrate a builtin program to Core BPF, there exists
no reliable method for loading a builtin's program account and performing
various checks to ensure the program account is configured as expected.
Being able to run these checks before fetching the builtin's program account
is extremely important for ensuring a smooth migration to Core BPF.
Summary of Changes
Within the
builtins
submodule, add a module specifically forcore_bpf_migration
,and inside of it create a new structure for loading a builtin's program account and
running checks, based on the type of builtin.
