Vector - error-free usage when length = 0 (#1291)

* Allow for error-free usage of length 0 CeedVectors

* Add tests for length 0 CeedVectors

* make clang-tidy happy

* remove unnecessary tests

basis - fix dimension mismatch for ApplyBasisAtPointsn

basis - fix tidy error

Attempting to resolve NVRTC and HIPRTC compilation errors

CEED_RESTRICTION_DEFAULT -> CEED_RESTRICTION_STANDARD

Update Julia/Python/Rust/Fortran bindings

Operator full assembly with oriented or curl-conforming element restrictions (RT or ND elements)

Improve element restriction for H(curl) spaces by reorganizing loops, including use of int8_t for tridiagonal matrix

enum CeedRestrictionType for CeedElemRestriction type

Element restriction for high-order (> 1) H(curl) elements requiring more general orientation transformations

Adds CeedElemRestrictionCreateCurlOriented which takes a tridiagonal element-wise transfo

Element restriction for high-order (> 1) H(curl) elements requiring more general orientation transformations

Adds CeedElemRestrictionCreateCurlOriented which takes a tridiagonal element-wise transformation matrix, typically with entries {-1, 0, 1}.

Merge pull request #1262 from CEED/jeremy/grad-at-points

Add CEED_EVAL_GRAD support for CeedBasisApplyAtPoints

op - use fallback parent for QFunction assembly if possible

op - clearer logic in CeedOperatorGetContextFieldLabel, avoid segfault for single operator w/o ctx case

basis - add num_comp to basis view output

doc - clarify error message and field compatibility requirements

fluids - drop unneeded calls to CeedOperatorSetNumQuadraturePoints

op - set restr num_qpts as op num_qpts when CEED_BASIS_COLLOCATED is first field

op - check for compatible num_qpts with CEED_BASIS_COLLOCATED

basis - add note about order for ApplyAtPoints

basis - minor refactor to put common Chebyshev code in utils

basis - add CEED_EVAL_GRAD support for CeedBasisApplyAtPoints

basis - add CeedBasisApplyAtPoints transpose mode

basis - add CeedBasisApplyAtPoints

Update LIBXSMM backend (#1248)

* Fix LIBXSMM kernel generation calls after 9c0e481 in https://github.com/libxsmm/libxsmm

* Update LIBXSMM interface to work with main branch after commit 1f4cdad (in preparation for v2)

* Allow user specified BLAS_LIB for LIBXSMM dependency in Makefile

* LIBXSMM does not require kernels to be released

See https://github.com/libxsmm/libxsmm/issues/783\#issuecomment-1596655284.

* Improvements for non-tensor CPU-based CeedBasisApply for q_comp > 1

* Revert previous commit since it's faster to apply in P*Q panels, remove an unncessary LIBXSMM kernel compilation

* Remove an unused macro

* make format

* Rely on LIBXSMM to cache JIT'd kernels

* LIBXSMM dispatched kernels for xsmm/serial backend

* Combine ceed-xsmm-tensor-fp64 and -fp32 into single file for all precisions

* Address PR comments

* Update GitLab CI LIBXSMM version
