When the work on the Flang driver started, we created 2 test
directories:
* flang/test/Frontend/
* flang/test/Driver/
That was mostly done to model what Clang was doing. In practice, we
stopped using "flang/test/Frontend/" early on and most Flang driver
tests are currently located in "flang/test/Driver/". This patch moves
the remaining tests from the latter into the former directory.
This change also means that we can re-use test input files, i.e.
flang/test/Frontend/Inputs/hello-world.f90 can be replaced with
flang/test/Driver/Inputs/hello.f90. To this end, the affected test is
updated (multiple-input-files.f90).

Until now we've been maintaining 2 test directories for Flang's drivers:
* test/Driver for `f18` (the current driver)
* test/Flang-Driver for `flang-new` (the new driver)
As we have started sharing tests between the drivers, this separation is
no longer required. This patch merges the two test directories. As
suggested in the review, moving forward we'll avoid having tests
specifically for the old driver.
A few notable changes:
* Driver/version-test.f90 and Driver/no-files.f90 are deleted. The
versions for the new driver are more robust, but tricky to share.
* Driver/write-module.f90 is deleted in favour of
Flang-Driver/write-module.f90 (see https://reviews.llvm.org/D97197
for more context)

When flang is invoked with no files it waits for input on stdin. Make it
print a message saying this to prevent the user being surprised.
