vboot: standardize on working data size
Previously, the size of memory made for vboot_working_data through the macro VBOOT2_WORK was always specified in each individual memlayout file. However, there is effectively no reason to provide this customizability -- the workbuf size required for verifying firmware has never been more than 12K. (This could potentially increase in the future if key sizes or algorithms are changed, but this could be applied globally rather than for each individual platform.) This CL binds the VBOOT2_WORK macro to directly use the VB2_WORKBUF_RECOMMENDED_DATA_SIZE constant as defined by vboot API. Since the constant needs to be used in a linker script, we may not include the full vboot API, and must instead directly include the vb2_constants.h header.
