Reapply "[Flang] Remove FLANG_INCLUDE_RUNTIME (#124126)"

This reverts commit 27539c3f903be26c487703943d3c27d45d4542b2. Retry
with new buildbot configuration after master restart.

Original message:

Remove the FLANG_INCLUDE_RUNTIME option which was replaced by
LLVM_ENABLE_RUNTIMES=flang-rt.

The FLANG_INCLUDE_RUNTIME option was added in #122336 which disables the
non-runtimes build instructions for the Flang runtime so they do not
conflict with the LLVM_ENABLE_RUNTIMES=flang-rt option added in #110217.
In order to not maintain multiple build instructions for the same thing,
this PR completely removes the old build instructions (effectively
forcing FLANG_INCLUDE_RUNTIME=OFF).

As per discussion in
https://discourse.llvm.org/t/buildbot-changes-with-llvm-enable-runtimes-flang-rt/83571/2
we now implicitly add LLVM_ENABLE_RUNTIMES=flang-rt whenever Flang is
compiled in a bootstrapping (non-standalone) build. Because it is
possible to build Flang-RT separately, this behavior can be disabled
using `-DFLANG_ENABLE_FLANG_RT=OFF`. Also see the discussion an
implicitly adding runtimes/projects in #123964.
