installd needs to kill profman if profman times out.
Bug: 242352919
Test: -
1. Add an infinate loop to profman.
2. Run `adb shell pm compile -m speed-profile com.android.chrome`
3. See profman being killed after 1 minute.

Brings in the io_uring class and associated restrictions and adds a new
macro, `io_uring_use`, to sepolicy.
In more detail, this change:
* Adds a new macro expands to ensure the domain it is passed can undergo a
type transition to a new type, `<domain>_iouring`, when the anon_inode
being accessed is labeled `[io_uring]`. It also allows the domain to
create, read, write, and map the io_uring anon_inode.
* Adds the ability for a domain to use the `IORING_SETUP_SQPOLL` flag
during `io_uring_setup` so that a syscall to `io_uring_enter` is not
required by the caller each time it wishes to submit IO. This can be
enabled securely as long as we don't enable sharing of io_uring file
descriptors across domains. The kernel polling thread created by `SQPOLL`
will inherit the credentials of the thread that created the io_uring [1].
* Removes the selinux policy that restricted all domains that make use of
the `userfault_fd` macro from any `anon_inode` created by another domain.
This is overly restrictive, as it prohibits the use of two different
`anon_inode` use cases in a single domain e.g. userfaultfd and io_uring.
This change also replaces existing sepolicy in fastbootd and snapuserd
that enabled the use of io_uring.
