[SYCL][CUDA] libdevice: add builtins (#1827)

Add some scalar math builtins to ptx/libdevice:

 - acos
 - asin
 - atan
 - cbrt
 - ceil
 - cos
 - erf
 - fabs
 - floor
 - fmax
 - fmin
 - lgamma
 - sqrt

sycl/test/built-ins/scalar_math.cpp test is split in two parts:

    scalar_math.cpp -> supported by cuda (no xfail)
    scalar_math_2.cpp -> unsupported

## Missing float builtins:

    atan2
    copysign
    fdim
    fma

for these it fails with
Unresolved extern function '_Z15__spirv_ocl_fmafff'

## Integer Builtins

-> need to make something similar too binary_builtin.inc for uint, int, long, ulong

## Geometry Functions

-> these aren't within _nv*. Maybe there is a way to reuse generic functions for these?
