MdeModulePkg/BootManagerMenuApp: Limit string drawing within one line

REF: https://bugzilla.tianocore.org/show_bug.cgi?id=3590

Limit the draw box always within the screen's column and row.
Limit the string drawing within one line.
For the incompleted string the last 3 characters in one line would
be replaced with "...".
