Summary:
1. Fix a memory leak in FaultInjectionTestFS in the stack trace related
code
2. Check status of all MultiGet keys before deciding whether an error
was swallowed, instead of assuming an ok status for any key means an
undetected error

Summary:
This PR implements a fault injection mechanism for injecting errors in reads in db_stress. The FaultInjectionTestFS is used for this purpose. A thread local structure is used to track the errors, so that each db_stress thread can independently enable/disable error injection and verify observed errors against expected errors. This is initially enabled only for Get and MultiGet, but can be extended to iterator as well once its proven stable.

Summary:
In the current code base, we can use FaultInjectionTestEnv to simulate the env issue such as file write/read errors, which are used in most of the test. The PR https://github.com/facebook/rocksdb/issues/5761 introduce the File System as a new Env API. This PR implement the FaultInjectionTestFS, which can be used to simulate when File System has issues such as IO error. user can specify any IOStatus error as input, such that FS corresponding actions will return certain error to the caller.
A set of ErrorHandlerFSTests are introduced for testing

Test Plan: pass make asan_check, pass error_handler_fs_test.
