  [DLCov] Origin-Tracking: Add config options (#143590)

This patch is part of a series that adds origin-tracking to the debugify
source location coverage checks, allowing us to report symbolized stack
traces of the point where missing source locations appear.

This patch adds the configuration options needed to enable this feature,
in the form of a new CMake option that enables a flag in
`llvm-config.h`; this is not an entirely new CMake flag, but a new
option, `COVERAGE_AND_ORIGIN`, for the existing flag
`LLVM_ENABLE_DEBUGLOC_COVERAGE_TRACKING`. This patch contains
documentation, but no actual implementation for the flag itself.
