Update CSL to eliminate dependence on `clock_gettime()` (#40499)
* Update SuiteSparse checksums to include `aarch64-apple-darwin`
* Update CSL to eliminate dependence on newer macOS support functions
Our compiler support libraries had been incorrectly built to use symbols
available only in macOS 10.12+; this update correctly configures them to
not use `clock_gettime()` and `mkostemp`.
