Use CONFIG_TCG as a project-wide flag to indicate that TCG is enabled

Within a specific compilation unit, we can remap CONFIG_TCG based on
CONFIG_TCG_TARGET. This allows us to avoid changes to the bulk of
the code base.
Within meson.build, while CONFIG_TCG may be set in config_host_data,
it may not be set within config_target. Thus all references to
CONFIG_TCG in source_set 'when:' need not be updated.
For the moment, CONFIG_TCG and CONFIG_TCG_TARGET are identical.

Shouldn't that rather go before the "#endif" instead?
Also, would it be possible to rather adjust scripts/make-config-poison.sh instead of
poisoning this switch manually?
No, I want to unconditionally poison it so that no other uses are ever
introduced.
