[Polly][Isl] Use isl::*::ctx instead of isl::*::get_ctx. NFC

[patacca]

Summary

This is part of an effort to reduce the differences between the custom C++ bindings used right now by polly in lib/External/isl/include/isl/isl-noxceptions.h and the official isl C++ interface.

Changes made:

• Use isl::*::ctx() instead of isl::*::get_ctx() (for example isl::space::ctx() instead of isl::space::get_ctx())
• Add isl:: namespace in front of isl types to avoid confusion (for example isl::space::ctx and isl::ctx
• isl-noexceptions.h has been generated by this https://github.com/patacca/isl/commit/b64e33c62d3fe7db506f6630f9e935b663f9c5a4

Could you add the reason for the added isl:: namespace to the commit message, like in this one:
https://github.com/patacca/isl/commit/b64e33c62d3fe7db506f6630f9e935b663f9c5a4

[suggestion] To avoid the "Lint: pre-merge checks" warnings in isl-noexceptions.h, you could make the generator emit // clang-format off (https://clang.llvm.org/docs/ClangFormatStyleOptions.html#disabling-formatting-on-a-piece-of-code)
