[DirectX] Bug fix for Data Scalarization crash (#118426)
Two bugs here. First calling `Inst->getFunction()` has undefined
behavior if the instruction is not tracked to a function. I suspect the
`replaceAllUsesWith` was leaving the GEPs in a weird ghost parent
situation. I switched up the visitor to be able to `eraseFromParent` as
part of visiting and then everything started working.
The second bug was in `DXILFlattenArrays.cpp`. I was unaware that you
can have multidimensional arrays of `zeroinitializer`, and `undef` so
fixed up the initializer to handle these two cases.

[DirectX] Split resource info into type and binding info. NFC (#119773)
This splits the DXILResourceAnalysis pass into TypeAnalysis and
BindingAnalysis passes. The type analysis pass is made immutable and
populated lazily so that it can be used earlier in the pipeline without
needing to carefully maintain the invariants of the binding analysis.

[DirectX] Data Scalarization of Vectors in Global Scope (#110029)
This change adds a pass to scalarize vectors in global scope into
arrays.
There are three distinct parts
1. find the globals that need to be updated and define what the new type
should be
2. initialize that new type and copy over all the right attributes over
from the old type.
3. Use the instruction visitor pattern to update the loads, stores, and
geps for the layout of the new data structure.
