Add Shaders/SharedData constant buffer and sampler strings

[Crauzer]

assets/shaders/shareddata.bin holds one X3DSharedData index plus 33 definition entries: 25 X3DSharedConstantBufferDef and 8 X3DSharedSamplerDef. Every one of those entry keys is currently unresolved, and every definition carries its own name string:

0xd8907437 = X3DSharedConstantBufferDef { name: string = "BonesCB" ... }
0xa6bded4f = X3DSharedSamplerDef        { name: string = "Clamp_No_Mip" ... }

Two path schemes reproduce 28 of the 33 keys:

Shaders/SharedData/ConstantBuffers/{leaf}     20 of 25
Shaders/SharedData/SharedSamplers/{leaf}       8 of 8

{leaf} is the name field with a trailing CB or _BUFFER removed, in the casing the file itself ships: BonesCB -> Bones, PerFramePixelCB -> PerFramePixel, IBL_CUBEMAP_SCALES_BUFFER -> IBL_CUBEMAP_SCALES. Names with no such suffix are used as is.

The flat Shaders/SharedData/{leaf} entries are now stale against shipped files so this fixes it.

Five constant buffers remain unresolved because their path leaf is not a simple transform of name: CharacterPerDrawVertexCB (0xa61a3acb), PostEffectPixelCB (0xb2db15bc), FontVertexCB (0xcb07a94b), VFXDynamicPerParticleInstanceCBVS (0xd234e251), VFXDynamicPerParticleInstanceCBPS (0xd243ecdb).

This work was done with the help of an LLM, and every entry was verified against shipped game data.

I was able to find the remaining entry paths:
CharacterPerDrawVertexCB => Shaders/SharedData/ConstantBuffers/CharacterPerDrawVS
PostEffectPixelCB => Shaders/SharedData/ConstantBuffers/PostEffects
FontVertexCB => Shaders/SharedData/ConstantBuffers/FontRendering
VFXDynamicPerParticleInstanceCBVS => Shaders/SharedData/ConstantBuffers/VFXDynamicPerParticleVS
VFXDynamicPerParticleInstanceCBPS => Shaders/SharedData/ConstantBuffers/VFXDynamicPerParticlePS
