Fix crash on boot due to vector size mismatch 

If NVIC_NUM_VECTORS is larger than the space allocated by the vector
table in ram (__ram_vector_table_size__) then the call to mbed_cpy_nvic
during boot will corrupt valid data, which can lead to a crash. This
patch fixes the declared number of vectors on the KL27Z, KL43Z and
KL82Z to fix this crash.
