Refine the GHCI macro into HAVE[_{INTERNAL, EXTERNAL}]_INTERPRETER

As discussed in #16331, the GHCI macro, defined through 'ghci' flags
in ghc.cabal.in, ghc-bin.cabal.in and ghci.cabal.in, is supposed to indicate
whether GHC is built with support for an internal interpreter, that runs in
the same process. It is however overloaded in a few places to mean
"there is an interpreter available", regardless of whether it's an internal
or external interpreter.

For the sake of clarity and with the hope of more easily being able to
build stage 1 GHCs with external interpreter support, this patch splits
the previous GHCI macro into 3 different ones:

- HAVE_INTERNAL_INTERPRETER: GHC is built with an internal interpreter
- HAVE_EXTERNAL_INTERPRETER: GHC is built with support for external interpreters
- HAVE_INTERPRETER: HAVE_INTERNAL_INTERPRETER || HAVE_EXTERNAL_INTERPRETER

Make `haddock_testsuite` respect `--test-accept`

Suppose you've made changes that affect the output of `haddockHtmlTest`
so that the following is failing:

    ./hadrian/build.sh -c --only=haddockHtmlTest test

Then, the following will accept new output for Haddock's test cases.

    ./hadrian/build.sh -c --only=haddockHtmlTest test --test-accept

You still do need to make sure those new changes (which show up in
Haddock's tree) get committed though.

Fixes #16694

Hadrian: teach the RTS that PROFILING implies TRACING

As discussed in #16744, both the Make and Hadrian build systems
have special code to always pass -eventlog whenever -prof or -debug
are passed. However, there is some similar logic in the RTS itself only
for defining TRACING when the DEBUG macro is defined, but no such logic
is implemented to define TRACING when the PROFILING macro is defined.
This patch adds such a logic and therefore fixes #16744.

rts/linker: Mmap into low memory on AArch64

This extends mmapForLinker to use the same low-memory mapping
strategy used on x86_64 on AArch64. See #16784.

rts/linker: Use mmapForLinker to map PLT

The PLT needs to be located within a close distance of
the code calling it under the small memory model.

Fixes #16784.

testsuite/mk/boilerplate.mk: rename 'ghc-config-mk' to 'ghc_config_mk'

Make/shell variable names which contain dashes can cause problems under
some conditions. The 'ghc-config-mk' variable from testsuite/mk/boilerplate.mk
that I made overridable (by Hadrian) in ba0aed2e was working as expected when
our Hadrian/Linux job was based off the deb8 Docker image, but broke when
I switched the job to use our deb9-based image, in 3d97bad6. The exact
circumstances/tool versions that trigger this problem are unknown, but
changing the variable's name to 'ghc_config_mk' lets us work around the issue.

This fixes the annth_compunits and annth_make test failures that showed up
when we switched the Hadrian/Linux job to use the deb9 environment.

rts/linker: Only mprotect GOT after it is filled

This fixes a regression, introduced by 67c422ca, where we mprotect'd the
global offset table (GOT) region to PROT_READ before we had finished
filling it, resulting in a linker crash.

Fixes #16779.

users-guide: Fix a few markup issues

Strangely these were only causing the build to fail in the aarch64-linux
job, despite Sphinx throwing errors in all jobs I checked.

Also changes some `#ifdef`s to `#if defined` to satisfy the linter.
