Integrate llvm/llvm-project@3b2233a (#23485)

Carrying reverts:

-
llvm/llvm-project@c6964b1
(breaks i1 tensor handling, see
#23463) (looked into by
@rkayaith)
-
llvm/llvm-project@34eb59d
(depends on
llvm/llvm-project@c6964b1)
-
llvm/llvm-project@75eecd2
(removes LLVMSupport from Python bindings CMake, breaks iree-dialects
build, see #23476) (looked into
by @RattataKing)

Dropped reverts:

llvm/llvm-project@a1d7cda

Other points of interest:

llvm/llvm-project@1de1a76
disallows implicit `const SmallVector` -> `MutableArrayRef`. [Affects
PCF](https://github.com/iree-org/iree/blob/a852a42734d182a7049433822c72607a06dca8fd/compiler/src/iree/compiler/Codegen/Dialect/PCF/Transforms/FuseConsumers.cpp#L630)
when we pass `params.slices`(coming from coming from `const
ConsumerFusionParams &params`) into `fuseIntoWriteSlices`; fix by
dropping extraneous const qualifier
