One of the mitigation methods for TAA[1] is to disable TSX
support on the host system.  Linux added a mechanism to disable
TSX globally through the kernel command line, and many Linux
distributions now default to tsx=off.  This makes existing CPU
models that have HLE and RTM enabled not usable anymore.

Add new versions of all CPU models that have the HLE and RTM
features enabled, that can be used when TSX is disabled in the
host system.

On systems disabling the features without those types defined
in cpu-maps users end up without modern CPU types in the list
of usable CPUs to use in the likes of virsh domcapabilities
or tools higher in the stack like virt-manager.

This adds:
-Cascadelake-Server-noTSX
-Icelake-Client-noTSX
-Icelake-Server-noTSX
-Skylake-Server-noTSX-IBRS
-Skylake-Client-noTSX-IBRS

The file was introduced in be03587a, but it was not added
to $(cpumap_DATA) at the time and so it didn't show up in the
distribution archive.

Vim has trouble figuring out the filetype automatically because
the name doesn't follow existing conventions; annotations like
the ones we already have in Makefile.ci help it out.
