x86/virt/tdx: Remove kexec docs

Browse Source 
Recent changes have removed the hard limitations for using kexec and
TDX together. So remove the section in the TDX docs.

Users on partial write erratums will need an updated TDX module to
handle the rare edge cases. The docs do not currently provide any
guidance on recommended TDX module versions, so don't keep a whole
section around to document this interaction.

machine check handler to tell user the machine check may be caused by
kernel bug on TDX private memory.
Kexec
~~~~~~~
Currently kexec doesn't work on the TDX platforms with the aforementioned
erratum. It fails when loading the kexec kernel image. Otherwise it
works normally.
