`%flang-new` was introduced in the early days of the new driver to make
a clear distinction between the tests for the current and the new
driver. We have since introduced `%flang` (compiler driver) and
`%flang_fc1` (frontend driver) as the long term solution. This has allowed
us to share tests between `flang-new` and `f18`. This patch replaces
all uses of `%flang-new` with `%flang` and `%flang_fc1`.
Some tests are reformatted so that all tests look uniform and are easier
to follow. Where possible, `! REQUIRES: new-flang-driver` is deleted so
that more tests can be shared with `f18`. To facilitate this,
`f{no-}implicit-none` are introduced in `f18` with semantics identical
to `flang-new`.
Two tests are deleted rather than updated:
* flang/test/Frontend/print-preprocess-C-file.f90
* flang/test/Frontend/print-preprocessed-file.f90
Instead, there is plenty of preprocessor tests in
flang/test/Preprocessing/.

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)
