  [SPIR-V] Support cl_ext_float_atomics and fix errors in definition of atomic_fetch_*_explicit builtins (#96767)

This PR:
* supports cl_ext_float_atomics by mapping atomic_fetch_add and
atomic_fetch_sub applied to float arguments to the corresponding
instructions from SPV_EXT_shader_atomic_float*_add, and
* fix errors in definition of atomic_fetch_*_explicit builtins by fixing
a valid number of arguments.
