Meta: Move compiler flags into standalone CMake files This way we can have all of them in a single place, similar to how we structure options added via the serenity_option() macro.

Meta: Link Lagom with LLD by default and allow configuring the linker This ports over the `LADYBIRD_USE_LLD` option from the standalone Ladybird build and generalizes it to work for mold as well: the `LAGOM_USE_LINKER` variable can be set to the desired name of the linker. If it's empty, we default to trying LLD and Mold on ELF platforms (in this order).

LibMedia: Use FFmpeg to decode more video formats VP9 continues to function, but this also allows AV1 to be decoded. With this commit, H.264 is still non-functional, as the decoder requires some extra initial data from the track definition in the Matroska file.

CMake: Link with `-Bsymbolic-non-weak-functions` if supported This flag makes the linker bind default-visibility functions locally, so that calls to them do not have to go through the PLT. This makes it impossible to override them by preloading a DSO. This was already the case partially due to `-fno-semantic-interposition`, however that flag is only able to optimize call sites that are in the same Translation Unit as the function definitions. This removes 80% of the PLT relocations in `libjs.so.serenity`. Obsoletes #20877
