x86/vector: Add vector domain debugfs support
Add the debug callback for the vector domain, which gives a detailed
information about vector usage if invoked for the domain by using rhe
matrix allocator debug function and vector/target information when invoked
for a particular interrupt.
Extra information foir the Vector domain:
Online bitmaps: 32
Global available: 6352
Global reserved: 5
Total allocated: 20
System: 41: 0-19,32,50,128,238-255
| CPU | avl | man | act | vectors
0 183 4 19 33-48,51-53
1 199 4 1 33
2 199 4 0
Extra information for interrupts:
Vector: 42
Target: 4
This allows a detailed analysis of the vector usage and the association to
interrupts and devices.
