SYCL-MLIR breaks on some sycl::vec<bool, size> constructs

[victor-eds]

Describe the bug

SYCL-MLIR does not fully support sycl::vec<bool, size> interface, leading to crashes. This might be related to SYCL-MLIR not being consistent when representing bool as i8 instead of i1 in memory.

To Reproduce

Compiling E2E tests using sycl::vec<bool, size> will lead to a crash:

clang++  -fsycl -fsycl-targets=spir64-unknown-unknown-syclmlir -w sycl/test-e2e/Basic/vector/bool.cpp -o - -S -emit-llvm -fsycl-device-only

cgeist: polygeist/tools/cgeist/Lib/CGCall.cc:145: void castCallerArgs(mlir::func::FuncOp, llvm::SmallVectorImpl<mlir::Value>&, mlir::OpBuilder&): Assertion `CalleeArgType == Args[I].getType() && "Callsite argument mismatch"' failed.

Note this is also true when passing -fpreview-breaking-changes:
