The goal of this patch is to reduce final shader code footprint to
hopefully reduce shader compile time (see #145347).
This also contains a pass over most shader file to remove unused
include or use more granular ones to reduce final shader code
length.
Testing with the same setup as #145347:
| | main (ms) | PR (ms) | Delta (ms) |
| -------- | ----------- | ------------ |------------ |
| Nvidia | 257 | 207 (1.24x) | 50 |
| Mesa AMD | 323 | 295 (1.09x) | 28 |
In barbershop test scene however the saving are not so noticeable:
| | main (s) | PR (s) | Delta (s) |
| -------- | ----------- | ------------ |------------ |
| Nvidia (OpenGL) | 40 | 39 (1.02x) | 1 |
| Nvidia (Vulkan) | 29 | 29 (1.0x) | 0 |

These lines can be removed to avoid parsing them.
This allow to keep the same processing for shared host files.
Also removes a few lines of code to reduce the size of
shader sources.
This also contains a rewrite of the include parsing using
the shader parser.

This allows to use `assert()` directly inside shader source.
The current implementation is just replacing it with a printf
that gives some information about the location of the assert.
It is not that much more helpful than a printf with a condition.
What is useful is that they are disabled by default. So they
can be sprinkle around and only turned on during debugging.
Adding shader name inside the assert report is not trivial and
could be added later (the shader name is only known at compile
time which is too late for string parsing).
Adding which drawcall produced the assert isn't trivial either.
It would require flushing the printf buffer for each drawcall
which might force synchronization and remove bugs.

Jittered Soft Shadows support.
Improves soft shadow quality at the cost of re-rendering shadow maps every sample.
Disabled by default in the viewport unless enabled in the Scene settings.

Tracing-only is the method used by default in EEVEE-Next.
Jitter-only is the method used by EEVEE-Legacy Soft Shadows.
Jitter+Over-blur combines both.
