[mlir][python] expose remaining Location inspection API (#192630)

Addresses #53169. Mirrors the Python bindings pattern used for Attribute
subclasses so that Location discrimination uses `isinstance`, and fills
two small gaps at the same time.

### Approach

Previously `Location` was a single nanobind class with `is_a_file`,
`is_a_name`, etc. predicates, plus field accessors for every kind
defined on the base class. This PR introduces a `PyConcreteLocation<T>`
CRTP template (parallel to `PyConcreteAttribute<T>`) and registers one
subclass per `LocationAttr` kind: `UnknownLoc`, `FileLineColLoc`,
`NameLoc`, `CallSiteLoc`, `FusedLoc`.

TypeID-based downcasting is implemented in `PyLocation::maybeDownCast`
(using `mlirAttributeGetTypeID(mlirLocationGetAttribute(...))`) and
called at the boundaries that return Location objects: `op.location`,
`value.location`, `Location.from_attr`, and the subclass getters

dlclose, dlsym), but it should be straightforward to extend to Windows.

[WebAssembly] Remove WasmEHFuncInfo (NFC) (#194972)

This removes `WasmEHFuncInfo` class.

This class was created to maintain the information of, "If an exception
is not caught by EHPad A, what is its next unwind destination?". Turns
out this information is already in the CFG.

After #130374, we use the common `findUnwindDestination`:
https://github.com/llvm/llvm-project/blob/113479d119a997e4c4c3eae63e087588c9662121/llvm/lib/CodeGen/SelectionDAG/SelectionDAGBuilder.cpp#L2107-L2164

Note that in case of `catchswitch`, we follow its unwind destination
chain and add all of them to the invoke BB's successors until it meets a
`cleanuppad`, which always catches an exception. And the order of the
successor is the order of the unwind destination chain. So an invoke
BB's successor list would be like: [normal destination, unwind EHPad 1,
unwind EHPad 2, unwind EHPad 3, ...] where EHPad 2 is the next unwind
destination if EHPad 1 does not catch an exception and so on. So if we
want to know what the current EHPad's next unwind destination is, we can

[RISCV] Remove isAsmParserOnly from isPseudo instructions. NFC (#194958)

isAsmParserOnly is only used to suppress DecoderEmiter, but that's
already supressed by isPseudo. The real usage for this should be for
instructions that have encoding information but we don't want to
disassemble.

Many of these pseudos are emitted from codegen meaning they aren't
really assembler only. So you can't argue this flag is good for
documentation either.
