compiler-rt, zigc: Use hidden visibility except when testing.
This prevents symbols from these libraries from polluting the dynamic symbol
tables of binaries built with Zig. The downside is that we no longer deduplicate
the symbols at run time due to weak linkage.

Closes #7935.
Closes #13303.
Closes #19342.
