Allow CeedScalar to be single precision (#788)

One can modify `ceed.h` to include `ceed-f32.h` and then use single precision. This is tested for C in CI and has been tested by developers with Rust,

Allow CeedScalar to be single precision (#788)

One can modify `ceed.h` to include `ceed-f32.h` and then use single precision. This is tested for C in CI and has been tested by developers with Rust, Julia, and Python. This interface is evolving and should be considered experimental at this time (thus lack of automated build support).

* Introduce CeedScalarType enum

* WIP changes to allow different definitions of CeedScalar

* Introduce new header files for float and double

* Only use avx tensor contract and MAGMA non-tensor basis if CeedScalar is double

* WIP changes to allow CeedScalar to be float

* WIP start trying to adjust test tolerances for float or double

* fix typos in comments

* install ceed-f32/64 headers

* Fix missing casts for hipMAGMA element restrictions

* make CeedQFunctionContextGetContextSize available for Python bindings

* Changes to Python bindings to allow CeedScalar to be float

* WIP adjust Python tests for float or double

* make style

* remove QFunctionContextGetContextSize from backend header

* Use quotes instead of <> in include statement

* Remove unncessary includes

* Update tolerances for tests

* [Julia] allow CeedScalar to be Float32

* [Julia] Use Preferences instead of custom build configuration

# Conflicts:
# julia/LibCEED.jl/src/C.jl

* [Makefile] Change definition of CC_VENDOR so it works with cross-compilation

* [Julia] Use Preferences in CI

# Conflicts:
# .github/workflows/julia-test-with-style.yml

* [Julia] Update docs about preferences

* [Julia] Add test/Project.toml workaround for Preferences

* Add CeedGetScalarType to get the type of CeedScalar at runtime

* [Julia] Move functions from Ceed.jl to LibCEED.jl

* [Julia] Add support for getting library path and scalar type at runtime

* [Julia] Minor change to checking if CUDA is loaded

* [Julia] Check correct CeedScalar types in basis functions

* [Julia] Fix tests comparing with output file

* [Julia] Change devtests to use CeedScalar instead of Float64

* Update test 402 so context will be same size in double or float

* Update tolerances for ceed examples

* [Julia] CUDA fixes

* remove unused variable in t208

* SchurDecomposition: do not compute tau on final iteration

* Update tolerances for some basis tests (for single precision)

* Make style

* Python style fixes for basis test

* Add single precision output for t300 and t320 and adjust checks; skip t541 in single

* Add LCOV exclusions after moving to new line

* fix spacing

* Python: make CEED_EPSILON available as libceed.EPSILON

* Python: optional parameter to specify different output file for test comparison

* Python: update tests' use of EPSILON and change test_300 output file for single precision

* Python: add convenience function for getting dtype corresponding to CeedScalar

* rust - add single precision support

* [Julia] Fall back on Float64 if CeedGetScalarType is not available

* [Julia] style

* Adjust tolerance for t301

* xsmm - add single precision support

* avx - add single precision support

* Add initial single precision support for MAGMA non-tensor basis

* Skip t300 and t320 in single precision; revert Python t300 changes

* Revert output changes for t300 and t320 in junit

* [Julia] Changes to autogenerated bindings for mixed precision

* [Julia] style

* [Julia] Check scalar type when changing libceed library path

The check is also performed when the package is loaded. This prevents having to
restart the Julia session twice

* [Julia] Require JLLWrappers version 1.3

This is needed to use Preferences to change the library path

* Add documentation page for precision development

Co-authored-by: Will Pazner <will.e.p@gmail.com>

* Cleanup from merge: remove old README

* Return CEED_ALIGN to backend.h

* Make Fortran compiler (FC) optional; empty skips Fortran tests

Use in Python and Rust builds, which may not have a Fortran compiler
installed and thus would produce confusing output.

* Add single precision CI test for Noether
