Preparation for the fix of
Bug#45097 Hang during recovery, redo logs for doublewrite buffer pages 

Non-functional change: move FSP_* macros from fsp0fsp.h to a new file
fsp0types.h. This is needed in order to be able to use FSP_EXTENT_SIZE 
in mtr0log.ic.

Preparation for the fix of
Bug#45097 Hang during recovery, redo logs for doublewrite buffer pages

Do not include unnecessary headers mtr0log.h and fut0lst.h in trx0sys.h
and include fsp0fsp.h just before it is needed. This is needed in order
to be able to use TRX_SYS_SPACE in mtr0log.ic.
