Update the SPIRV `mlir-translate` translations to translate to/from
`spirv.module` instead of `builtin.module`. This simplifies the
translation since the code no longer needs to walk the module looking
for a SPIRV module, however it requires passing `-no-implicit-module` to
all the tests.

To unify the naming scheme across all ops in the SPIR-V dialect, we are
moving from spv.camelCase to spv.CamelCase everywhere.
