Implements support for ENOMEM (errno 12) across the network stack:
- Added NOMEM to Network::Errno enum
- Added NOMEM = 12 to sockets Errno enum
- Added translation case in sockets_translate.cpp
This is the first step towards addressing the 0.0 FPS bug that occurs
when the system runs out of memory during socket operations. Previously,
these operations would trigger an unimplemented assertion, causing the
emulator to halt. Now the error will be properly propagated to the guest
application.

Reverts overly restrictive storage buffer validation and size calculation
that was causing rendering issues in The Legend of Zelda: Tears of the
Kingdom, particularly in underground/depth areas. The simplified approach:
- Uses GetMemoryLayoutSize() instead of manual page probing
- Removes unnecessary 4GB memory bounds validation
- Streamlines address translation and alignment handling
This fixes numerous reported cases of missing or corrupted rendering in
TOTK's underground areas where storage buffer operations are heavily used
for depth-related effects.

Implements proper reference counting for binder objects based on the official
documentation. This adds both weak and strong reference counting support to
the IBinder interface and its implementations (BufferQueueProducer and
BufferQueueConsumer).
The implementation follows the documented behavior where:
- type 0 affects weak references
- type 1 affects strong references
- During initialization: {addval=1, type=0} followed by {addval=1, type=1}
- For onFirstRef: {addval=1, type=1}
- For onLastStrongRef: {addval=-1, type=1}
Reference counters are implemented using std::atomic to ensure thread safety.

Relaxes validation checks in the NVDRV GPU service and improves error notifier
handling to prevent potential hangs. Key changes:
- Remove strict size validation in SetErrorNotifier
- Relax GPFIFO entry count validation to only check for non-zero values
- Add proper error notifier state tracking in GPU class
- Improve debug logging messages
The previous strict validation was causing issues with some games like ACNH.
These changes maintain necessary checks while being more permissive with
edge cases that don't impact functionality.
Technical changes:
- Store error notifier state in GPU class for future implementation
- Remove upper bound check on GPFIFO entries
- Simplify error notifier setup flow
This should resolve hanging issues while maintaining core functionality.
