fix(dev-mode) always add dist-types

[bitflower]

With the help of @simonhaenisch I could find the reason why #2349 is happening.

It is because here

stencil/src/compiler/config/outputs/validate-dist.ts

Line 47 in 4c70fdd

if (config.buildDist) {

the buildDist is false and the output target DIST_TYPES is not added in dev-mode. It is however needed later on.

This causes this condition to return false:

stencil/src/compiler/transpile/ts-config.ts

Line 8 in 63595bc

declaration: config.outputTargets.some(isOutputTargetDistTypes),

and declaration becomes false - which is not allowed in combination with composite: true.

I first tried to tackle it via this line by removing the devMode condition but it seems too related to other (global) decisions you've made maybe:

stencil/src/compiler/config/validate-config.ts

Line 52 in 253894d

setBooleanConfig(config, 'buildDist', 'esm', !config.devMode || config.buildEs5);

So my solution is to always add the output target DIST_TYPES no matter the mode (dev or prod).

This is a huge blocker for us - would love to find a solution!

Thanks a lot!
