[mlir][tosa] Add support for CONV2D_BLOCK_SCALED operator (#172294)

This commit adds support for an MXFP CONV2D operation,
CONV2D_BLOCK_SCALED, added to the specification in
https://github.com/arm/tosa-specification/commit/408a5e53f5a7357adef7121ba3cc88e2225d4231.

This includes:
- Operator definition
- Addition of the EXT_MXFP_CONV extension
- Verification logic for the operator
- Output shape inference for the operator
- Validation checks to ensure compliance with the TOSA specification.

AArch64: Use getLibcallImplCallingConv more consistently (#176377)

the LibcallImpl.

AMDGPU/GlobalISel: Regbanklegalize rules for G_UNMERGE_VALUES

Move G_UNMERGE_VALUES handling to AMDGPURegBankLegalizeRules.cpp.
Fix sgpr S16 unmerge by lowering using shift and using S32.
Previously sgpr S16 unmerge was selected using _lo16 and _hi16 subreg
indexes which are exclusive to vgpr register classes.
For remaing cases we do trivial mapping, assigns same reg bank
to all operands, vgpr or sgpr.

vchiq: fix build with clang 21

When compiling vchiq with clang 21, the following -Werror warning is
produced:

    sys/contrib/vchiq/interface/vchiq_arm/vchiq_arm.c:728:27: error: default initialization of an object of type 'VCHIQ_QUEUE_MESSAGE32_T' with const member leaves the object uninitialized [-Werror,-Wdefault-const-init-field-unsafe]
      728 |                 VCHIQ_QUEUE_MESSAGE32_T args32;
          |                                         ^
    sys/contrib/vchiq/interface/vchiq_arm/vchiq_ioctl.h:151:40: note: member 'elements' declared 'const' here

          |                                               ^

While the warning is formally correct, the 'args32' object is
immediately initialized after its declaration. Therefore, suppress the
warning.

[AMDGPU] si-peephole-sdwa: Handle V_PACK_B32_F16_e64 (WIP)

Change si-peephole-sdwa to eliminate V_PACK_B32_F16_e64 instructions
by changing the second operand to write to the upper word of the
destination directly.

[AMDGPU] Enable ISD::{FSIN,FCOS} custom lowering to work on v2f16

Currently ISD::FSIN and ISD::FCOS of type MVT::v2f16 are legalized by
first expanding and then using a custom lowering on the resulting f16
instructions. This ordering prevents using packed math variants of the
instructions introduced by the legalization (e.g. the multiplication),
if available, and makes it difficult to eliminate the packing of the
results by using SDWA form; previous attempts to deal with the latter
situation in the si-peephole-sdwa pass were unwieldly since it was
necessary to reconstruct the association between the source and target
vectors.

Change the legalization action for ISD::FSIN and ISD::FCOS of type
MTF::v2f16 to Custom and change the custom intrinsic lowering to deal
with the v2f16 for the intrinsics introduced in this way.
