Pool Vector Dead Link on 4.0

[TheYellowArchitect]

PoolVectorArrays were a thing in 3.x it seems
https://docs.godotengine.org/en/stable/classes/class_poolvector2array.html?highlight=poolvector2array

They don't exist in 4.x https://docs.godotengine.org/en/latest/classes/class_poolvector2array.html?highlight=poolvector2array
PackedVectorXArrays replaced them.

Yet, in the docs, there is still a location they are referenced:
https://docs.godotengine.org/en/latest/development/cpp/core_types.html?highlight=poolvector#allocating-memory
pool_vector.h especially is a dead link and has been long deleted. memory.h seems to have completely remade it to use MemoryStaticPool (can't confirm as I can't read the source code)

Related:

• Convert all references and instances of PoolVector to Vector godot#36311
• Every tutorials that refers to PoolVector (C++) or Pool*Array (scripting) should be reviewed for 4.0 #3192

My suggestions to close this and the above issue:

• Make https://docs.godotengine.org/en/latest/classes/class_poolvector2array.html?highlight=poolvector2array redirect to https://docs.godotengine.org/en/latest/classes/class_packedvector2array.html?highlight=packedvector2array
  Same applies for Vector3 and whatever converted from pool -> packed

• Update the https://docs.godotengine.org/en/latest/development/cpp/core_types.html?highlight=poolvector#allocating-memory with whatever is the new memory return/format

Pool*Vector was replaced by Packed*Vector in 4.0. The documentation referencing them should be rewritten (not just renamed) as how packed vectors work internally is different from pooled vectors. You can find some information about it in Core refactoring progress report #1.

#10329 removed the references to Pool*Array and PoolVector, but I'm leaving this open for now to track the documentation of alternatives to Vector<> in 4.x.

Redirects may be out of scope at this point, since we're so far into the 4.x release cycle.
