[PATCH v7 0/3] RISC-V SBI-backed SerialLib

["Andrei Warkentin" <andrei.warkentin@intel.com>]

Hello,

Here are three patches that provide a SerialLib backed by SBI console. 
Both legacy and DBCN mechanisms are supported in various execution environments and have been tested with UART and HTIF consoles.

MdePkg reviewers: please review MdePkg.dsc changes.

A CI run is at https://github.com/tianocore/edk2/pull/4252

Compared to v6:

- Unify the two SerialLib implementations under one directory and
  factor out the code somewhat.
- Sunil's feedback on correctness.

Compared to v5:

Rename components as per Michael Kinney's suggestions.

Compared to v4:

(not sent out). CC MdePkg maintainers, fix copyright date in SecMain.c.

Compared to v3

EccCheck fixes. Add MdePkg infs to DSC.

Compared to v2:
- Probes legacy extension as well.
- Encode supported module types in the INF file. This is done using LIBRARY_CLASS,
  as MODULE_TYPE cannot encode multiple types, so MODULE_TYPE is retained as BASE.
- Update INF version and generate brand new GUIDs instead of editing them.
- Checked that all patches retain ^M endings.
