Subject: [PATCH] Remove intermedia obj files once build finished (#14361)

### Description
Remove intermedia obj files and reenable cache

### Motivation and Context
Recently, training_debug_x64 pipeline often failed due to not enough
space.
It could free nearly 8G space by deleting obj files.
So, the compilation cache can be reenabled
