Summary:
This diff adds the ability to skip translation with `... && neg ( pattern)` logic so that we can skip translation of some files if the source does not contain a pattern.
Note that `skip-translation` expects a list of patterns as disjunctions:

whereas we want the ability to have conjuctions inside.
## Context
Immutability analysis requires analyzing generated code which might have `Immutable` annotations. When analysing fbandroid, we skip all generated code:
```
"skip-translation": [
{
"source_contains": "generated",
"language": "Java"
}
],
```
However, rather than analyzing all generated code (which might be expensive across all targets) by removing the above, with this diff, we only analyze generated code that doesn't contain e.g. `Immutable` and skip all other generated code as before:
```
"skip-translation": [
{
"source_contains": "generated",
"source_not_contains": "Immutable",
"language": "Java"
}
],
```
