[PATCH v2] MdeModulePkg/Include: Long debug string is truncated to 104 char

[PATCH v2] MdeModulePkg/Include: Long debug string is truncated to 104 char

[Cosmo Lai]

From: Cosmo Lai <cosmo.lai@intel.com>

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3986

The EFI_STATUS_CODE_DATA_MAX_SIZE is defined as 200 in MdeModulePkg.
After reducing 96byte buffer for variable parameters it is limited to
only 104 char debug string. This is a non-necessary limitation.
It can be set to 0x200 to follow MAX_EXTENDED_DATA_SIZE (also 0x200)
which is used in ReportStatusCodeLib to support longer debug string.
