MdeModulePkg/SdMmcOverride: Add GetOperatingParam notify phase

https://bugzilla.tianocore.org/show_bug.cgi?id=1882

The new notify phase allows platform to configure additional
bus parameters in addition to parameters that can already be configured
with capability override. Specifically we allow to configure bus width,
clock frequency and driver strength. If platform doesn't wish to configure
some of the parameters it can left it on default values and driver will
assume it's standard behavior with respect to those parameters.
The definition of the SD_MMC_BUS_MODE has been extended to
incorporate SD card default speed and high speed.

Tests on Marvell boards were also performed by Marcin Wojtas
<mw@semihalf.com>:

https://edk2.groups.io/g/devel/message/42999

Board 1 (out of tree): SD - OK, MMC - OK
Board 2: (Armada80x0McBin): SD - OK, MMC - OK
Board 3: (Armada70x0Db): SD - problems, MMC - OK

Please note that the problem on Armada70x0Db SD devices are introduced by
adding new types of SD bus modes, a subsequent patch within edk2-platforms
repository will be proposed to address it.
