Renaming the option is based on discussions in https://reviews.llvm.org/D101122.
It is normally not a good idea to rename driver flags but this flag is
new enough and obscure enough that it is very unlikely to have adopters.
While we're here also drop the `<kind>` metavar. It's not necessary and
is actually inconsistent with the documentation in
`clang/docs/ClangCommandLineReference.rst`.

This change simplifies `clang/lib/Frontend/CompilerInvocation.cpp`
because we no longer need to manually parse the flag and set codegen
options in the frontend. However, we still need to manually parse the
flag in the driver because:
* The marshalling infrastructure doesn't operate there.
* We need to do some platform specific checks in the driver
that will likely never be supported by any kind of marshalling
infrastructure.

The new `-fsanitize-address-destructor-kind=` option allows control over how module
destructors are emitted by ASan.
The new option is consumed by both the driver and the frontend and is propagated into
codegen options by the frontend.
Both the legacy and new pass manager code have been updated to consume the new option
from the codegen options.
It would be nice if the new utility functions (`AsanDtorKindToString` and
`AsanDtorKindFromString`) could live in LLVM instead of Clang so they could be
consumed by other language frontends. Unfortunately that doesn't work because
the clang driver doesn't link against the LLVM instrumentation library.
