Unable to disable any warnings besides JSII_5018_RESERVED_WORD

[Dzuelu]

"Full" list of warnings can be found here https://github.com/aws/jsii-compiler/blob/main/src/warnings.ts and only include the reserved-word warning. Ideally someone should be able to disable any warnings if they are not applicable to their use case. Ideally would like to propagate these options to disable warnings to projen.

PR created to add all warnings and a test that any new warnings must be added to the list in #1838
