Currently we have ld_libdir_abs which defaults to false. In that case,
both the mangohud shell wrapper, as well as the json files, reference
the DSOs directly without any path component.
This means that at run-time the dynamic linker, vulkan loader as well as
pressure-vessel will need to jump through hoops and figure out the
bitness of the DSO, whether one wants the 32 or 64bit one and even then
there will be confusing messages like:
fatal: /usr/lib/libMangoHud.so: wrong ELF class: ELFCLASS32
When set to true, as seen in the in-tree build.sh we'll append empty
path to LD_LIBRARY_PATH (bad), the full path with the $LIB token will be
used with LD_PRELOAD (good) and json files (bad).
Since we are generating separate json files, we can use the actual path
(while $LIB currently works, it's not really strict json nor documented
as supported). We can also drop the dubious LD_LIBRARY_PATH manipulation
This basically reinstates the prepend_libdir_vk=true option that was
dropped earlier.

This will allow us to remove the $LIB from the json files and simplify
the related lib handling.

This introduces support to overlay FCAT markers on top of other HUD elements.
For more information about nVidia's FCAT tool see: https://nvidia.com/en-us/geforce/technologies/fcat/technology
This patch includes support for the existing parameter infrastructure and it is fully dynamic.
Squashed commit:
Refactor FCAT to use existing parameter handling infrastructure
With this patch the FCAT overlay should be hooked up into the normal
parameter handling infrastructure. This includes support for
configuration file options, which are also part of this commit.
Added missing options and rearranged the way they appear under legacy layout plus minor fixes:
* Added some default values after `=`
* Commented out options with default values
* Unified style
`gl_size_query = viewport` - specify what to use for getting display size. Options are "viewport", "scissorbox" or disabled. Defaults to using glXQueryDrawable.
`gl_bind_framebuffer = 0` - (re)bind given framebuffer before MangoHud gets drawn. Helps with Crusader Kings 3.
`gl_dont_flip = 1` - don't swap origin if using GL_UPPER_LEFT. Helps with Ryujinx.
* Added (commented out `fps_sampling_period`, `version` and `engine_version`)
* Commented out `legacy_layout` by default and added `=false` if one want to enable new layout
* Unified VSync, FPS, RAM and other minor names while at it
* Added space after comments sign for options that were missing it to unify formatting
