Draft release notes:

New features

• Add CeedOperatorCreateAtPoints which evaluates the CeedQFunction at arbitrary locations in each element, for use in Particle in Cell, Material Point Method, and similar methods.
• Add CeedElemRestrictionGetLLayout to provide L-vector layout for strided CeedElemRestriction created with CEED_BACKEND_STRIDES.
• Add CeedVectorReturnCeed and similar when parent Ceed context for a libCEED object is only needed once in a calling scope.
• Enable #pragma once for all JiT source; remove duplicate includes in JiT source string before compilation.
• Allow user to set additional compiler options for CUDA and HIP JiT.
  Specifically, directories set with CeedAddJitSourceRoot(ceed, "foo/bar") will be used to set -Ifoo/bar and defines set with CeedAddJitDefine(ceed, "foo=bar") will be used to set -Dfoo=bar.

Interface changes

• Add bool field type for CeedQFunctionContext and related interfaces to use bool fields.
• CEED_BASIS_COLLOCATED removed; users should only use CEED_BASIS_NONE.
• Remove unneeded pointer for CeedElemRestrictionGetELayout.
• Change QFunction source include file handling in JiT compilers
  • Add CEED_RUNNING_JIT_PASS compiler definition for wrapping header files that device JiT compilers cannot read
  • Users should now prefer #include <ceed/types.h> rather than #include <ceed.h> in QFunction source files
• Require use of Ceed*Destroy() on Ceed objects returned from Ceed*Get*().
