This changes the DEFINE_VIRT_MACHINE macro to use the common
helpers for constructing versioned symbol names and strings,
bringing greater consistency across targets.

The various targets which define versioned machine types have
a bunch of obfuscated macro code for defining unique function
and variable names using string concatenation.
This addes a couple of helpers to improve the clarity of such
code macro.

Thomas proposed a new deprecation and removal policy for versioned
machine types that would see them liable for deletion after 6 years:

This changes the DEFINE_VIRT_MACHINE macro to use the common
helpers for constructing versioned symbol names and strings,
bringing greater consistency across targets.
A DEFINE_VIRT_MACHINE_AS_LATEST helper is added so that it
is not required to pass 'false' for every single historical
machine type
The new deprecation and deletion policy for versioned machine types is
being introduced in QEMU 9.1.0.
Under the new policy a number of old machine types (any prior to 2.12)
would be liable for immediate deletion which would be a violation of our
historical deprecation and removal policy

Versioned machines live for a long time to provide back compat for
incoming migration and restore of saved images. To guide users away from
usage of old machines, however, we want to deprecate any older than 3
years (equiv of 9 releases), and delete any older than 6 years (equiva
of 18 releases).

This calls the MACHINE_VER_DELETION() macro in the machine type
registration method, so that when a versioned machine type reaches
the end of its life, it is no longer registered with QOM and thus
cannot be used.
The actual definition of the machine type should be deleted at
this point, but experi
This extends the deprecation policy to indicate that versioned machine
types will be marked deprecated after 3 years, and then subject to
removal after a further 3 years has passed.

This calls the MACHINE_VER_DEPRECATION() macro in the definition of
all machine type classes which support versioning. This ensures
that they will automatically get deprecation info set when they
reach the appropriate point in their lifecycle.
