Refactor - Share RBPF config and syscall registry globally

[Lichtso]

Problem

Currently the RBPF config and syscall registry are created for each Instruction of a Transaction, which is wasteful and makes it hard to control the config in one place. Note, that this PR does not yet implement the feature activation recompilation phase nor does it adjust the RBPF config based on feature activations.

Summary of Changes

• Adds LoadedPrograms::program_runtime_environment_v1 which is created in Bank::finish_init() and used in Bank::load_program().
• Merges get_programdata_offset_and_deployment_offset() into load_program_from_account().
• Renames create_loader() to create_program_runtime_environment().
