Currently, all of the modules are built from a single Bazel package.
This complicates integration with the vendor build because the
Android build system builds the modules individually.
Split the modules into their own Bazel packages to align more closely
with the Android build system's expectations and easy to hook bazel build.

Fence error use case may require that later fence in tx queue
be signaled with error before earlier fence. HW Fence Driver
provides limited support for this scenario by providing a way
to swap the first two entries of client Tx Queue.

Add HW Fence Driver support to notify waiting clients of fence error in
HLOS. This is a requirement by clients that do not have Rx Queue. Such
clients can register a fence error callback function with data that will
be passed back with callback.
The fence error callback function is called by HW Fence Driver when:
1. Client registers for a fence already signaled with error.
2. Error is signaled for a fence that the client registered to wait on.

Current implementation allows ioctl to deregister hw-fence client with
client_id that does not match hw_sync_obj. This can cause a double-free
if user-space deregisters the wrong file descriptor by mistake.
Instead, fail the ioctl early if it has these invalid parameters.

Some hw fence driver clients require the ability to call the
'msm_hw_fence_update_txq' API to update the queue payload without
updating the 'write_index' member within the hfi header. These clients
also need to receive the index at which the payload is written within
the queue.
This change adds support for this requirement by adding a device-tree
property to configure this behavior for each client. The 'tx_wm' member
within the hfi header is used to track in software the place where the
payloads are within the queue for clients that skip the update to the
'write_index' member.
