It should be possible to pass values with `any Sendable` as arguments
to `inout` parameters that expect `Any`. This is pretty much the same
as an l-value conversion.

`any Sendable` -> `Any` in generic argument positions should be
supported for l-value and inout types as well otherwise it won't
be possible to call setters and mutating methods.
In non-strict concurrency mode when `@preconcurrency` declarations
are involved `any Sendable` should be treated as `Any` in generic
argument positions to support passing types that (partially) adopted
concurrency annotations to types that haven't yet done so.
