zld: redo symbol resolution in objects
...
Store only globals and undefs at the linker level, while all locals
stay scoped to the actual object file they were defined in. This is
fine since the relocations referencing locals will always be resolved
first using the local symbol table before checking for the reference
within the linker's global symbol table.
This also paves the way for proper symbol resolution from within static
and dynamic libraries.

Refactor link/wasm.zig to use offset table
...
This refactor inserts an offset table into wasm's data section
where each offset points to the actual data region.
This means we can keep offset indexes consistant and do not
have to perform any computer to determine where in the data section
something like a static string exists. Instead during runtime
it will load the data offset onto the stack.

stage2: restructure LLVM backend
...
The LLVM backend is now structured into 3 different structs, namely
Object, DeclGen and FuncGen. Object represents an object that is
generated by the LLVM backend. DeclGen is responsible for generating
a decl and FuncGen is responsible for generating llvm instructions
from tzir in a function.

And then the big one: updating astgen.zig to use the new memory layout.
