25c53f08a6 elf: redo strings management in the linker 
* atom names - are stored locally and pulled from defining object's
  strtab
* local symbols - same
* global symbols - in principle, we could store them locally, but
  for better debugging experience - when things go wrong - we
  store the offsets in a global strtab used by the symbol resolver

3fc6fc6812 std.builtin.Endian: make the tags lower case 
Let's take this breaking change opportunity to fix the style of this
enum.

d890e81761 mem: fix ub in writeInt 
Use inline to vastly simplify the exposed API.  This allows a
comptime-known endian parameter to be propogated, making extra functions
for a specific endianness completely unnecessary.

4bc88dd116 link: support exporting constant values without a Decl 
The main motivating change here is to prevent the creation of a fake
Decl object by the frontend in order to `@export()` a value.

Instead, `link.updateDeclExports` is renamed to `link.updateExports` and
accepts a tagged union which can be either a Decl.Index or a
InternPool.Index.

098a07dc45 link.Elf: fix UAF in lowerAnonDecl 
The main problem being fixed here is there was a getOrPut() that held on
to a reference to the value pointer too long, and meanwhile the call to
`lowerConst` ended up being recursive and mutating the hash map,
invoking undefined behavior.

caught via #17719

e1248b693f elf: allocate PHDR table always succeeding the EHDR 
While this is a less flexible approach to being able to
allocated the PHDR anywhere in file, it is sadly generally expected
by the tooling in the wild.
