Adds a new healing symptom for virology and an immunosupressant chemical (#96305)

## About The Pull Request

Adds a new virology symptom:
Agressive Healing - The virus provides a healing effect, scaling with
the severity of the virus, always. However despite being a positive
symptom it has a severity of 1, meaning that unless something is done
about it your positive virus will eventualy be killed by your immune
system.
It also provides medium stat boosts and decreases the stelth value of
the virus.

Also adds a new chem, ImmunoSilence, which prevents viruses from being
cured naturaly while it is being metabolised. It is made from ammonia
and diphenhydramine.

Suggestions for better flavour and more balanced numbers welcome.

## Why It's Good For The Game

It is a symptom that allows for pretty interesting gameplay, as it can
both just work as a stat boost for other symptoms at the cost of having
to use immunosupressing medicine (as alternatively tour virus will die
faster, especialy if it is positive), and/or alternatively provide
strong healing at the cost of having to endure with some negative
symptoms.
The new chem is meant to synergise with this symptom but can be
obviously used for other goals.
