meson: control using LD Version Scripts

LD version scripts are meant to be used when visibility attributes can't be used*, and have compatibility issues with other linkers. When a symbol in the linker script is missing, LD will ignore it, mold will warn, and LLD will error. This patch is only an optional flag for now in-case of packagers using these scripts and due to an issue between rust + meson 1 2. Although the size difference in rusticl is negligible, (114M v 117M), it still exposes internal details.

*if only using the global & local sections, as is done in mesa. For specific version sections, the symver attribute is the replacement, which clang doesn't support yet.

This should provide a potential fix for #8003 (closed) and #8359
