ShellPkg: acpiview: Allow disabling consistency checks (-q flag)

The current documentation for the acpiview UEFI shell tool states
that the '-c' flag enables consistency checks on ACPI table data.
However, these checks are enabled anyway by default.

This patch keeps ACPI table validation as a default option, but it
makes it possible to turn ACPI table validation off by setting the
newly-introduced '-q' flag. Consequently, the '-c' flag is removed.

The remaining code changes in this patch make a number of consistency
checks optional (but enabled by default):
1. ACPI table field offset mismatch.
2. ACPI table field validation functions provided in the ACPI_PARSER
   arrays.
3. Table checksum computation.
