* 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
* Relax authority signer check for lookup table creation
* cli: support creating lookup tables without authority signer
* add another create lookup table ix function
* improve help message
* Adds methods based on instruction_account_index to InstructionContext.
Removes methods which are based on index_in_instruction.
* Adjusts program-runtime.
* Adjusts runtime.
* Adjusts bpf loader.
* Adjusts built-in programs.
* Adjusts program-test and bpf tests.
* Introduces result return types to get_data_mut(), set_data() and set_data_length() of BorrowedAccount.
* Introduces result return types to set_owner(), set_lamports() and set_executable() of BorrowedAccount.
* Adds transaction_context and instruction_context where invoke_context.get_keyed_accounts() is used.
* Use instruction_context.get_instruction_data() instead of an explicit parameter.
* Removes instruction_data parameter from Executor::execute().
* Removes instruction_data parameter from ProcessInstructionWithContext.
