devel/tex-synctex: Update to 1.21.0
- Remove various patches to improve and ease maintenance by bringing them
together and excluding unnecessary components directly in the Makefile patch
from their corresponding macros. Couldn't think of a better way, especially
since we're using the original TeX Live codebase to extract and build the SyncTeX
component separately.
- Add synctex_version.h header.

Differential_Revision: D32264
```
Dependant ports editors/texworks and graphics/zathura are updated in
in D32265 and D32266, respectively. PORTREVISION of editors/gummi,
net-mgmt/netmagis-www, and print/texlive-full are also incremented. For
texlive-full, though, I am not sure if I've done it correctly.
In the meanwhile, as explained above, old patchfiles are deleted as I've
brought configuration arguments into the main Makefile. This way, we can
maintain the port more easily in future.
