1278ac71 - [NFC][GlobalISel] Pass `APInt` by const reference (#157827)

[NFC][GlobalISel] Pass `APInt` by const reference (#157827) Change `SpecificConstantMatch` constructor and `isBuildVectorConstantSplat` overloads to take `const APInt&` instead of by value to avoid unnecessary copies, especially for wide integers.
