9937874b - [clangd][HLSL] Add hover support for vector swizzle and matrix element access (#212741)

[clangd][HLSL] Add hover support for vector swizzle and matrix element access (#212741) Hovering over a vector swizzle expression (e.g. `.xyz`) or a matrix element access (e.g. `._m00`) previously produced no hover information, since ExtVectorElementExpr and MatrixElementExpr were not handled in getHoverContents(const Expr *E). This patch adds support for these expressions within `getHoverContents` by extracting the accessor name and resolved type for both node kinds. Fixes #212612
