[mlir][vector] Tighten the semantics of vector.gather (#135749)

This patch restricts `vector.gather` to only accept tensors and memrefs
as valid sources. Currently, the source is typed as `AnyShaped`, which
also includes vectors—allowing the following (invalid) construct to pass
verification:

```mlir
  %0 = vector.gather %base[%c0][%indices], %mask, %pass_thru
       : vector<16xf32>, vector<16xi32>, vector<16xi1>, vector<16xf32> into vector<16xf32>
```
(Note: the source %base here is a vector, which is incorrect.)

In contrast, `vector.scatter` currently only accepts memrefs, so some
asymmetry remains between the two ops. This PR is a step toward aligning
their semantics.

The LLVM Compiler Infrastructure

OpenSSF Scorecard OpenSSF Best Practices libc++

Welcome to the LLVM project!

This repository contains the source code for LLVM, a toolkit for the construction of highly optimized compilers, optimizers, and run-time environments.

The LLVM project has multiple components. The core of the project is itself called “LLVM”. This contains all of the tools, libraries, and header files needed to process intermediate representations and convert them into object files. Tools include an assembler, disassembler, bitcode analyzer, and bitcode optimizer.

C-like languages use the Clang frontend. This component compiles C, C++, Objective-C, and Objective-C++ code into LLVM bitcode -- and from there into object files, using LLVM.

Other components include: the libc++ C++ standard library, the LLD linker, and more.

Getting the Source Code and Building LLVM
