Update base for Update on "[ET-VK] Replace Uniform buffers with push constants for permute op"

This diff replaces uniform buffers with push constants for permute op in the Vulkan backend of Executorch. The changes include updating the GLSL code to use push constants instead of uniform buffers and updating the C++ code to pass the sizes as push constants to the shader.

 ## Current flows
 
 The ArmBackend has a two stage process,
-- Compile to TOSA to rationalise the graph into known hardware support profiles. Currently this is to v0.80.0 TOSA BI with specific concern to a subset which gives support on Ethos-U55, the target of the initial prototype efforts.
-- Lower via the ethos-u-vela compilation flow which takes TOSA v0.80.0 as an input and produces a low level commandstream for the hardware which is then passed via the delegate to the ethos-u-core-driver for direct execution.

 The ArmPartitioner is currenly used to ensure the operations converted are Ethos-U compatible, but will be extended to offer spec-correct TOSA Base inference and TOSA Main Inference generation in future.
