Previously, VRAM TTM resource manager debugfs entries (vram0_mm / vram1_mm)
were created globally in the XE debugfs root directory. But technically,
each tile has an associated VRAM TTM manager, which it can own.
Let's create VRAM memory manager debugfs entries directly under each tile's
debugfs directory for better alignment with the per-tile memory layout.

Switch the debugfs code to use scope-based runtime PM where possible,
for consistency with other parts of the driver.

We will want to use this helper function in other files.

Due to initial lack of per-tile debugfs directories, the ggtt file
attribute was created as per-GT file. Fix that since now we have
proper per-tile directories.

Our drm-based suballocator is implemented per-tile so it is better
to show its debug information also per-tile debugfs directory, not
under per-gt directory as it is done today.
To allow adding more per-tile attributes, prepare necessary helper
functions, like we already did for per-gt or per-uc attributes.
