Subject: [PATCH] symengine: revision bump (llvm 15.0.0)

Also, apply a patch to make sure we link with the `libLLVM` shared
library instead of the static libraries.

Trying to use the static libraries causes build failures because Apple's
`ld` cannot read the LTOed object files.

An alternative workaround is to do something like

    ENV.append_to_cflags "-fuse-ld=lld" if OS.mac?

in the formula.

Closes #106925.
