Reduce duplicated masking raster code by replacing with c++ templates
this change does not noticeably impact performance (< error bound).
Binary Size diff: 218379 -> 217851 (-0.5kb)
Reduce duplicated image raster code between scaler approaches.
Although this allows for a function call per pixel,
this change does not noticeably impact performance (< error bound).
Binary Size diff: 222541 -> 218379 (-4kb)
Reduce excessive gradient filling code duplication by employing C++ template method.
This change does not affect performance or binary size adversely.
Binary Size Diff: 223399 -> 222693 (-706)
Unify textmap methods that are overly duplicated with each other.
Still trying to simplifying raster code so that thorvg could introduce
the a bunch of masking method code nicely.
This reduces the size like: 214773 -> 212843 (-2kb)
Compact blending instructions by distinquish the
shape & images. since we gurantee the shape color is
premultiplied alpha.
As a result, this enhanced performance by 0.002s in examples/Performance
on my local machine.
This also contains code cleanup chores.

It currently defaults to false,
but it will default to true in future releases of meson.

The CompositeMethod now includes the newly supported InvLumaMask option:
The source pixels are converted to grayscale (luma values),
and the complement of the target's pixels is alpha blended.
As a result, only the part of the source where the grayscale
is not covered by the target is visible.

@Issue: https://github.com/thorvg/thorvg/issues/404
There are two branches for completing stroke composition between the canvas and sw_engine.
It is necessary to centralize the task on the canvas engine side so that
we can maintain the logic without confusion.
When combining Shape, Stroke, and AlphaMasking, there is a missing
composition step which results in an incorrect output as expected by the user.
This problem is resolved by introducing shape fill and stroking composition.
