I missed these attributes when I added the wrapper for GPUFuncOp in
fbdd98f74f0d.

Add builders on the Python side that match builders in the C++ side, add tests for launching GPU kernels and regions, and correct some small documentation mistakes. This reflects the API decisions already made in the func dialect's Python bindings and makes use of the GPU dialect's bindings work more similar to C++ interface.

The func dialect provides a more pythonic interface for constructing
operations, but the gpu dialect does not; this is the first PR to
provide the same conveniences for the gpu dialect, starting with the
gpu.func op.

Implement the feature about perf by stage(llvm-ir -> isa, isa->binary).
The results will be stored into the properties, then users can use them
after using GpuModuleToBinary Pass.

objects (#95292)
This patch adds the `#gpu.kernel_metadata` and `#gpu.kernel_table`
attributes. The `#gpu.kernel_metadata` attribute allows storing metadata
related to a compiled kernel, for example, the number of scalar
registers used by the kernel. The attribute only has 2 required
parameters, the name and function type. It also has 2 optional
parameters, the arguments attributes and generic dictionary for storing
all other metadata.
The `#gpu.kernel_table` stores a table of `#gpu.kernel_metadata`,
mapping the name of the kernel to the metadata.
Finally, the function `ROCDL::getAMDHSAKernelsELFMetadata` was added to
collect ELF metadata from a binary, and to test the class methods in
both attributes.
Example:
```mlir
gpu.binary @binary [#gpu.object<#rocdl.target<chip = "gfx900">, kernels = #gpu.kernel_table<[
#gpu.kernel_metadata<"kernel0", (i32) -> (), metadata = {sgpr_count = 255}>,
#gpu.kernel_metadata<"kernel1", (i32, f32) -> (), arg_attrs = [{llvm.read_only}, {}]>
]> , bin = "BLOB">]
```
The motivation behind these attributes is to provide useful information
for things like tunning.

expand-arith-ops.mlir fails on windows, but this is unrelated to this PR

This commit removes all LLVM dialect typed pointers from the lit tests.
Typed pointers have been deprecated for a while now and it's planned to
soon remove them from the LLVM dialect.

python (#70428)
Added missing register_translations in python to replicate the same in
the C-API
Cleaned up the current calls to register passes where the other calls
are already embedded in the mlirRegisterAllPasses.
