Rename all shader cache strings to pipeline cache

After Hades, both OpenGL and Vulkan use a pipeline cache instead of single stages of the graphics pipeline. Renamed the Remove menu entries to match.

emit_spirv_context_get_set: Fix Get FrontFace return value

vk_blit_screen: Fix non-accelerated texture size calculation

Nested demote branches add complexity with combining the condition if it has not been initialized yet. Skip them for the time being.

This is only needed on select drivers when a fragment shader discards/demotes.

vp9_types: Remove unusued VP9 info struct members

ngct: Stub NGCT:U service

Some drivers misread data when demotes are interleaved in the program. This moves demote branches to be checked at the end of the program.

Revert "logging: Display backtrace on crash"

Populates the current_address, subnet_mask, and gateway fields from the selected network interface.

The IR expects GetAttribute to return an F32 value. This case was returning a U32 instead.
