[Mlir-commits] [mlir] Include <cstdlib> in Toy Lexer examples. (PR #110449)

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 1b5f6916199ce09244cdb52c6911f2028e6ca95a which removed inclusion of `<cmath>` and thus broke transitive inclusion of `<stdlib.h>` in these headers.

Subject: [PATCH] Include <cstdlib> in Toy Lexer examples.

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 1b5f6916199ce09244cdb52c6911f2028e6ca95a
which removed <cmath> and thus broke transitive inclusion
of <stdlib.h> in these headers.
