Include <cstdlib> in Toy Lexer examples. (#110449)

vonosmas · web-flow · commit 8ab50da589fd · 2024-09-30T13:20:32.000-05:00
These files all use `strtod` - make sure to include a proper header for this function. Otherwise, building MLIR fails on some systems after the recent commit 1b5f691 which removed inclusion of `<cmath>` and thus broke transitive inclusion of `<stdlib.h>` in these headers.
