[MC-260457] block_display entities do not inherit transformation nbt data properly from /summon

Description:
When summoning a block display, 'left_rotation' 'right_rotation' 'translation' and 'scale' must ALL be included in the transformation tag, or the block display will use the default values.

Replication:
using

/summon block_display ~ ~ ~ {transformation:{left_rotation:[0f,0f,0f,1f],right_rotation:[0f,0f,0f,1f],translation:[0f,0f,0f],scale:[2f,1f,1f]},block_state:{Name:"minecraft:dirt"}}

works properly and summons a block with the proper scale

/summon block_display ~ ~ ~ {transformation:{left_rotation:[0f,0f,0f,1f],translation:[0f,0f,0f],scale:[2f,1f,1f]},block_state:{Name:"minecraft:dirt"}}

fails to apply the scale

/summon block_display ~ ~ ~ {transformation:{right_rotation:[0f,0f,0f,1f],translation:[0f,0f,0f],scale:[2f,1f,1f]},block_state:{Name:"minecraft:dirt"}}

also fails to apply the scale

/summon block_display ~ ~ ~ {transformation:{left_rotation:[0f,0f,0f,1f],right_rotation:[0f,0f,0f,1f],scale:[2f,1f,1f]},block_state:{Name:"minecraft:dirt"}}

also fails to apply the scale

/summon block_display ~ ~ ~ {transformation:{left_rotation:[0f,0f,0f,1f],right_rotation:[0f,0f,0f,1f],translation:[5f,0f,0f]},block_state:{Name:"minecraft:dirt"}}

fails to apply the translation.
