tcg: Remove TCI experimental status

Browse Source 
The following commits (released in v6.0.0) made raised the
quality of the TCI backend to the other TCG architectures,
thus is is not considerated experimental anymore:
- c6fbea47664..2f74f45e32b
- dc09f047edd..9e9acb7b348
- b6139eb0578..2fc6f16ca5e

Other host architectures are not supported. It is possible to build QEMU on an
unsupported host architecture using the configure ``--enable-tcg-interpreter``
option to enable the experimental TCI support, but note that this is very slow
and is not recommended.
Other host architectures are not supported. It is possible to build QEMU system
emulation on an unsupported host architecture using the configure
``--enable-tcg-interpreter`` option to enable the TCI support, but note that
this is very slow and is not recommended for normal use. QEMU user emulation
requires host-specific support for signal handling, therefore TCI won't help
on unsupported host architectures.
Non-supported architectures may be removed in the future following the
:ref:`deprecation process<Deprecated features>`.
