QObjects must be deleted if the QCoreApplication is being destroyed.
This was previously done by implementing custom code in qtbase and
other modules. So unify it and introduce a Q_APPLICATION_STATIC,
based on the Q_GLOBAL_STATIC, which centralises the logic.
Since we still have a few remaining living QObjects,
this comes in handy to fix those as well.

The relevant MS system calls (say they) don't support date formatting
for years < 1601 (but apparently do in fact) and the year field of the
data structure is unsigned, so can't support years < 0. As a result,
the windows back-end for QSystemLocale failed for negative years.
So replace year < 1601 with a place-holder and substitute after
formatting.
Added new tests (based loosely on one in qtdeclarative that failed) to
verify that this actually works. These reveal that macOS also fails to
handle negative years; marked as expected failure there pending a fix.

The documentation for QProcessEnvironment's default constructor
says:
This constructor creates an empty environment. If set on a
QProcess, this will cause the current environment variables
to be removed.
This is not the case however, because setting such an environment
for a process is equivalent to not setting an environment at all
and the child process is executed with parent's environment.
It is still possible starting from Qt 6.2.0 to create an empty
environment by adding a variable to a null environment and removing
it, but that's cumbersome, and the comparison operator says that
it is equal to the null environment but it is obviously behaving in
a different way.
This change adds an additional constructor to QProcessEnvironment
that can be used to construct a null environment, and changes the
default constructor to produce an empty environment. The comparison
operator is changed to correctly distinguish between such objects.
This is a behavior change, but the current behavior is broken
and this is unlikely to affect working code.
[ChangeLog][QtCore][QProcessEnvironment] An additional constructor
was added to explicitly create an object that when set on QProcess
would cause it to inherit the environment from parent (this was
formerly the behavior of a default-constructed QProcessEnvironment,
which will now (as documented) actually give a process an environment
with no variables set). A new method inheritsFromParent() was added
to test for such objects.

When declaring metatypes, the metatype system tries to detect if the
comparison operators for the given type exist and automatically register
them. In case of QHash, the equality operator was enabled if the value
type provides one. But the implementation needs equality operator of
the key type as well. As a result, when the key type has no equality
operator, the metatype system detects that the equality operator is
available for the QHash itself, but the compilation for metatype
registration fails when trying to instantiate the code that uses
equality operator for the key. This is fixed by enabling equality
operators for the QHash only when both the key and value types provide
one.
The same issue existed also for QMultiHash, with the difference, that
QMultiHash didn't have the constraints even on the value type. So added
checks for both.

A few systems, like OpenWRT, may strip the section table off the
resulting binaries (see [1]), making it impossible for us to pinpoint
the exact location of the Qt plugin metadata. This commit moves the meta
data to a location that is identifiable even in fully stripped binaries:
an ELF note.
By naming our section ".note.qt.metadata", we instruct the linker to
place it along the other notes and to mark it in the program header
section. Another advantage is that the notes are usually in the very
beginning of the file, as they are used by the dynamic linker itself, so
we'll need to read much less of the full contents.
The unit test is modified not to attempt to strip the plugin of
debugging data. In fact, we add something to the end that would,
otherwise, be matched as (invalid) metadata.
The following was produced with GCC 11 and GNU binutils ld 2.36.1.
Section Headers:

The Qt metadata note is 4-byte aligned and can thus be found in the
second note section, which spans from 0x02d8 to 0x02d8+0xac=0x0384.
GNU readelf -n can even show it:

description data: 01 06 03 81 bf ...... ff
I chose 0x7451 as the prefix for our notes, even though they're already
namespaced by the owner in the first place, because eu-readelf
mistakenly tries to interpret note 1 as a GNU ABI tag regardless of
owner. The owner name was chosen to be 12 bytes long, so the ELF note
header is 24 bytes in total. There's no space wasted because the payload
needs to be aligned to 32-bit anyway and I didn't want to use only 4
characters (header total size 16 bytes) so we'd skip the "GNU" note on
size, without string comparison. And I couldn't think of a 4-character
representative string ("QtP" ?).
