Fix PCD parsing for PCDs that have a single quote in them

[NishanthSanjeevi]

The PCD parsing regex pattern failed for PCDs that had a single quote

For example,
gEfiMdePkgTokenSpaceGuid.PcdSingleQuote|"eng'fraengfra"|VOID*|0x0000002f
CRITICAL - EXCEPTION: Too few parts: ['PcdSingleQuote|"eng'fraengfra"', 'VOID*', '0x0000002f']

The new pattern should allow the usage of single quotes
