libpdx_uds: Serialize access to connection socket between threads
Added a mutex to allow only one client thread to perform atomic
send-request/receive-responce actions.
Also added a unit test that perfroms multiple parallel client requests
to the same service to ensure it can handle multithreaded access
correctly.
Bug: 37443070
Test: `libpdx_uds_tests` pass

libpdx_uds: Fix RPC channel ID allocation to not recycle values as often
The value of channel ID for PDX service on UDS transport was actual file
descriptor value for the data socket. Since channels are open and closed
constantly, it is quite often that channel ID is being reused immediately,
so it is almost impossible to use `cid` as unique identifier for objects
being passed around.
Instead, we now use monotonically growing channel ID value.
To prevent the possibility of using channel ID as the socket FD and vice
versa, changed all helper functions that used to take socket_fd as an int
to explicitly use BorrowedHandle which disables implicit conversion from
int (and hence makes it impossible to mistakenly pass in the channel ID).
Bug: 37082296
Test: `m -j32` succeeds for sailfish-eng
Ran libpdx_uds_tests on the device -> all pass
Device boots and CubeSea and VrHome render correctly with vr_flinger

libpdx: Add support for more event bits.
- Add generic abstraction for multiple event bits with an implementation-
defined mechanism to deliver the bits.
- Update ServiceFS backend to pass through event bits.
- Implement EPOLLIN, EPOLLPRI, and EPOLLHUP event bit for UDS backed.
Bug: 34466748
Test: Build/flash system; observe stable operation.
