[Flang][NFC] Split runtime headers in preparation for cross-compilation. (#112188)

Split some headers into headers for public and private declarations in
preparation for #110217. Moving the runtime-private headers in
runtime-private include directory will occur in #110298.

* Do not use `sizeof(Descriptor)` in the compiler. The size of the
descriptor is target-dependent while `sizeof(Descriptor)` is the size of
the Descriptor for the host platform which might be too small when
cross-compiling to a different platform. Another problem is that the
emitted assembly ((cross-)compiling to the same target) is not identical
between Flang's running on different systems. Moving the declaration of
`class Descriptor` out of the included header will also reduce the
amount of #included sources.

* Do not use `sizeof(ArrayConstructorVector)` and
`alignof(ArrayConstructorVector)` in the compiler. Same reason as with
`Descriptor`.

* Compute the descriptor's extra flags without instantiating a
Descriptor. `Fortran::runtime::Descriptor` is defined in the runtime
source, but not the compiler source.

* Move `InquiryKeywordHashDecode` into runtime-private header. The
function is defined in the runtime sources and trying to call it in the
compiler would lead to a link-error.

* Move allocator-kind magic numbers into common header. They are the
only declarations out of `allocator-registry.h` in the compiler as well.

This does not make Flang cross-compile ready yet, the main goal is to
avoid transitive header dependencies from Flang to clang-rt. There are
more assumptions that host platform is the same as the target platform.

[flang][runtime] 'A' output editing for LOGICAL (#89817)

We support 'A' output editing for INTEGER and REAL as an extension; it
turns out to be used as well for LOGICAL in application code.

This test case depends on the stderr output of a `nullptr` being
"(null)". However, it is empty string on AIX.

This test case depends on the stderr output of a `nullptr` being

This PR is to initialize the `sourceFileName_` to be a specific string
to avoid that.

[flang] use 1-based dim in transformational runtime error msg

Flang transformational runtime was previously reporting conformity
issues in a zero based fashion to describe which dimension is non
conformant. This may confuse Fortran user, especially when the message
is about a dimension other than the first one.

[flang] Allow more concurrently open NEWUNIT= values, with recycling

Add a header-only implementation of Briggs & Torczon's fast small
integer set data structure to flang/include/flang/Common, and use
it in the runtime to manage a pool of Fortran unit numbers with
recycling. This replaces the bit set previously used for that
purpose. The set is initialized on demand with the negations of
all the NEWUNIT= unit numbers that can be returned to any kind
of integer variable.

For programs that require more concurrently open NEWUNIT= unit
numbers than the pool can hold, they are now allocated with a
non-recycling counter. This allows as many open units as the
operating system provides.

Many of the top-line comments in flang/unittests/Runtime had the
wrong path name. I noticed this while adding a unit test for the
fast integer set data structure, and cleaned them up.

[flang] Skip `Fortran STOP:` before message when NO_STOP_MESSAGE is set

In 'STOP bye bye', do not print 'Fortran STOP:` before 'bye bye' when
NO_STOP_MESSAGE environment variable is set at runtime.

Also only exit with code 1 in StopStatementText if this is an ERROR STOP.
This matches other compiler behaviors.

Move STOP related unit tests in their own test file and add new tests to
cover this change.

The 'A' edit descriptor once served as a form of raw I/O of bytes

didn't exist until F'77). This usage was especially common for
output of numeric variables that had been initialized with Hollerith.
