mesa: Don't use memcpy() in _mesa_texstore() for float depth texture data
because float depth texture data needs clamping to [0.0, 1.0]. Let the
_mesa_texstore() fallback to slower path.
Fixes Khronos GLES3 CTS tests:
shadow_execution_vert
shadow_execution_frag
V2: Move the check to _mesa_texstore_can_use_memcpy() function.
Add check for floating point data types.
