[bazel] Fix test files so they compile individually
Most of these are pretty innocuous changes, like adding
missing headers or moving certain includes behind #ifdefs.
A non-trivial change is creating tests/SkSLDSLUtil.cpp
so tests/SkSLDSLOnlyTest.cpp can depend on it instead
of depending on another Test file. We would like our
test files to be independent of each other as much
as possible.
