Allow "-exclude-all-symbols" to be passed through the zig cc/c++ frontend as a linker flag.
Zig Version
0.14.0
Steps to Reproduce and Observed Behavior
I was trying to use zig-bootstrap and modify the shell script slightly to build a dynamically linked library version of llvm, and a Zig that links to it. The problem is when building llvm using pre-existing zig, there are symbol clashes. I read in #15107 that you can pass "-exclude-all-symbols" to avoid having all symbols exported. I think this might fix it, but the clang-like frontend that cmake would use (zig cc/c++) doesn't support the flag (eg. -wL...), and calls it unsupported.
Expected Behavior
Exhibit the same, working behaviour as if you ran "zig lld-link -exclude-all-symbols ..."
Here is a copy of the build file after the modifications:
