[mlir][spirv] Add support for SPV_ARM_tensors (#144667)

This patch introduces a new custom type `!spirv.arm.tensor<>` to the
MLIR SPIR-V dialect to represent
`OpTypeTensorARM` as defined in the `SPV_ARM_tensors` extension.

The type models a shaped tensor with element type and optional shape,
and implements the
`ShapedType` interface to enable reuse of MLIR's existing shape-aware
infrastructure.

The type supports serialization to and from SPIR-V binary as
`OpTypeTensorARM`, and emits the
required capability (`TensorsARM`) and extension (`SPV_ARM_tensors`)
declarations automatically.

This addition lays the foundation for supporting structured tensor
values natively in SPIR-V and
will enable future support for operations defined in the
`SPV_ARM_tensors` extension, such as
`OpTensorReadARM`, `OpTensorWriteARM`, and `OpTensorQuerySizeARM`.
