Select the Log Level for the Event Log Dump on Measured Boot at build time.
Builds in Debug mode with Measured Boot enabled might run out of trusted
SRAM. This patch allows to change the Log Level at which the Measured Boot
driver will dump the event log, so the latter can be accessed even on
Release builds if necessary, saving space on RAM.
