Make SkRuntimeShaderBuilder safe for reuse

Previously, if you snapped off a shader and then changed uniforms
(without drawing & flushing), we'd trigger the SkData assert about
calling writeable_data when not-uniquely-owned. Now we lazily copy the
SkData when necessary.

Includes unit test that previously failed.
