* Bumps solana_rbpf to 0.2.34
* Removes generic UserError from EbpfError.
* Uses ProgramResult for syscalls.
Removes use sites of the question_mark! macro by wrapping the call method of SyscallObjects.
* Uses InvokeContext as syscall context object directly.
* Replaces bind_syscall_context_object() by a parameter in the constructor.
* Inlines bind_syscall_context_objects() at its only call site.
* BorrowedAccount: add set_data_from_slice(), make set_data() take owned values
set_data() used to take a slice and would force alloc+copy if the caller
has owned values (eg account creation, account lookup table).
Expose set_data_from_slice() for callers that have slices, and switch
set_data() to taking an owned Vec.
* BorrowAccount: refactor common accounts_update_delta code in helper method
* BorrowedAccount: add extend_from_slice()
This allows avoiding copies appending entries to account lookup tables.
* BorrowedAccount: remove unnecessary ifs around update_accounts_resize_delta
* Adds the feature disable_cpi_setting_executable_and_rent_epoch.
* Adds the feature gate for disable_cpi_setting_executable_and_rent_epoch.
* Removes TEST_EXECUTABLE_LAMPORTS.
* Test that is_executable and rent_epoch are ignored.
