[build-script] Propagate libdispatch-cmake-options

PR #25085 [1] enabled building and installing the static variant of the
libdispatch library in build-script-impl. This broke the
`tsan-libdispatch-test` preset [2].

Let's make sure we pass along the options specified in
`libdispatch-cmake-options` when building the static variant.
