56791: sql: rearrange fields in miscellaneous structs to reduce memory usage r=yuzefovich a=yuzefovich

This commit simply moves around fields in several structs throughout the
sql directory in order to reduce the amount of padding required to get
the alignment fields. All of these optimizations have been found by
using github.com/orijtech/structslop tool. As a result of this code
movement, most of the modified structs moved into a smaller object size
class (the exceptions are some variations of the generated structs in
colexec which didn't change in size).

Release note: None
