44c40237 - [GPU][Custom] Offload temp buffers to global memory in GPU ext kernels (#35250)

[GPU][Custom] Offload temp buffers to global memory in GPU ext kernels (#35250) This commit adds support for allocating global memory buffers for custom GPU kernels used with the OpenVINO GPU plugin. Key changes: - Adds support for internal buffer definitions from custom layer XML. - Supports dynamic buffer sizing based on input and output shapes. - Allocates and manages intermediate buffers automatically. - Ensures consistent buffer mapping for custom GPU kernels. This enables custom GPU operations to handle larger temporary data more efficiently using global memory. ### Tickets: CVS-170201 ### AI Assistance: - *AI assistance used: no*
