Everywhere: Add sv suffix to strings relying on StringView(char const*)
...
Each of these strings would previously rely on StringView's char const*
constructor overload, which would call __builtin_strlen on the string.
Since we now have operator ""sv, we can replace these with much simpler
versions. This opens the door to being able to remove
StringView(char const*).
No functional changes.

LibPDF: Fix "incorrect" matrix multiplication in Renderer
...
Incorrect is in quotes because the spec (both 1.7 and 2.0) specify this
multiplication as it was originally! However, flipping the order of
operations here makes the text in all of my test cases render in the
correct position.
The CTM is a transformation matrix between the text coordinate system
and the device coordinate system. However, being on the right-side of
the multiplication means that the CTM scale parameters don't have any
influence on the translation component of the left-side matrix. This
oddity is what originally led to me just trying this change to see if
it worked.

LibPDF: Add support for the CalRGB ColorSpace
...
This isn't tested all that well, as the PDF I am testing with only uses
it for black (which is trivial). It can be tested further when LibPDF
is able to process more complex PDFs that actually use this color space
non-trivially.
