Implement the second entry point for GET_ENVIRONMENT_VARIABLE. Reuse
existing bits and pieces wherever possible.
This patch also increases CFI_* error codes in order to avoid conflicts.
GET_ENVIRONMENT_VARIABLE is required to return a status of 1 if an
environment variable does not exist and 2 if environment variables are
not supported. However, if we add status codes for that they will
conflict with CFI_ERROR_BASE_ADDR_NULL and CFI_ERROR_BASE_ADDR_NOT_NULL,
which are also 1 and 2 at the moment. We therefore move all CFI error
codes up (an arbitrary) 10 spots to make room. Hopefully this isn't
a problem, since we weren't matching the CFI error codes that gfortran
uses anyway. It may still be an issue if any other runtime functions
will need to return a status of 1 or 2, but we should probably deal with
that when/if it occurs.

Recommit https://reviews.llvm.org/D109813 and
https://reviews.llvm.org/D109814.
This implements the second and final entry point for GET_COMMAND_ARGUMENT,
handling the VALUE, STATUS and ERRMSG parameters.
It has a small fix in that we're now using memcpy instead of strncpy
(which was a bad idea to begin with, since we're not actually interested
in a string copy).
This reverts commit 0446f1299f and
df6302311f.
There's a warning on flang-aarch64-latest-gcc related to strncpy using
the result of strlen as a bound. I'll recommit with a fix.
Implement the final part of GET_COMMAND_ARGUMENT, i.e. the handling of
ERRMSG. This uses some of the infrastructure in stat.h and gets rid of
the magic numbers that we were using for return codes.

Move the closure of the subset of flang/runtime/*.h header files that
are referenced by source files outside flang/runtime (apart from unit tests)
into a new directory (flang/include/flang/Runtime) so that relative
include paths into ../runtime need not be used.
flang/runtime/pgmath.h.inc is moved to flang/include/flang/Evaluate;
it's not used by the runtime.
