fix(build): don't export all symbols to dynamic symbol table

[littledivy]

Currently, we use -rdynamic for exporting Node API symbols to the symbol table. -rdynamic will export all symbols, that means previously unused functions will not be optimized away introducing a lot of binary bloat. It can be seen here:

This patch uses -exported_symbol and --export-dynamic-symbol link flags (not as universal as -rdynamic) to only mark Node API symbols to be put in the dynamic symbol table.

This needs GNU ld 2.35 and the CI is on 2.34 right now 😭
