Cheaper logcontext debug logs (random_string_insecure_fast(...)) (#19094) 
Follow-up to https://github.com/element-hq/synapse/pull/18966

During the weekly Backend team meeting, it was mentioned that
`random_string(...)` was taking a significant amount of CPU on
`matrix.org`. This makes sense as it relies on
[`secrets.choice(...)`](https://docs.python.org/3/library/secrets.html#secrets.choice),
a cryptographically secure function that is inherently computationally
expensive. And since https://github.com/element-hq/synapse/pull/18966,
we're calling `random_string(...)` as part of a bunch of logcontext
utilities.

Since we don't need cryptographically secure random strings for our
debug logs, this PR is introducing a new `random_string_insecure_fast(...)`
function that uses
[`random.choice(...)`](https://docs.python.org/3/library/random.html#random.choice)
which uses pseudo-random numbers that are "both fast and threadsafe".

Use Python's secrets module instead of random (#9984) 
Functionally identical, but more obviously cryptographically secure.
...Explicit is better than implicit?

Avoids needing to know that SystemRandom() implies a CSPRNG, and
complies with the big scary red box on the documentation for random:

> Warning:
>   The pseudo-random generators of this module should not be used for
>   security purposes. For security or cryptographic uses, see the
>   secrets module.

Remote dependency on distutils (#9125) 
`distutils` is pretty much deprecated these days, and replaced with
`setuptools`. It's also annoying because it's you can't `pip install` it, and
it's hard to figure out which debian package we should depend on to make sure
it's there.

Since we only use it for a tiny function anyway, let's just vendor said
function into our codebase.

d9aa645f86 Reduce size of joined_user cache 
The _get_joined_users_from_context cache stores a mapping from user_id
to avatar_url and display_name. Instead of storing those in a dict,
store them in a namedtuple as that uses much less memory.

We also try converting the string to ascii to further reduce the size.
