Add size support for Form Field inputs

[bhoppers2008]

Resolving this issue will add sizes to Form Field input type controls.

MTK's request: Christian was asking about our plans for Typography.. They will be doing some analysis of their tickets in Q3, some text needs to be 'scale' proportionally but it does not make sense to switch density. I know he has spoken with Hopwood, Benjamin (CIB, DEU) on this. I suggested when they do their analysis of their requirements, if we can get some visibility we can opine on the suggested approach. ie. should Markets own this or is this something missing from our side ?

i think it would offer value as a salt option.

offering sizes of components so teams can achieve different levels of affordance would be a good addition in the context of financial experiences. it would also provide a better alternative to mixing densities, since we could guarantee alignments.

would need some time to identify exactly what size gets applied to.

for example for form field, perhaps size only drives field height, and nothing else.
