Shift to boost asio library

This commit shifts vpd manager from sdbusplus event loop to
boost io_context event loop.
The shift was done to have a more flexible way to perform
async Dbus calls.
For example read/write of vpd data can be performed
asynchronously.

It also removes dependency of Manager class on the interface
class created as a part of Phosphor-Dbus-Interface repo.

Test:
- Introspect com.ibm.VPD.Manager /com/ibm/VPD/Manager to ensure
that all the methods exposed under com.ibm.VPD.Manager interface
matches to the ones documented under PDI repo.

- Make DBus call to each of the exposed api to ensure that the
funcation calls are working fine.

-To ensure bios handler call back is working.
Stop vpd-manager service.
Stop pldm service.
Start vpd-manager service
Start pldm service.
Should recieve callback.

-To ensure gpio call back
std::cout were added to callback function being trigerred on
timer expiration and the same were verified in journal.

manager: Sync pvm_clear_nvram BIOS Attribute

This commit adds support to synchronize the pvm_clear_nvram BIOS
attribute to bit 2 in the UTIL/D1 keyword of the motherboard VPD.

The attribute will be used by PHYP to determine when to clear their
NVRAM content.

A value of "Disabled" in the BIOS attribute maps to the D1:2 bit being 0
and a value of "Enabled: maps to the D1:2 bit being 1.

This commit adds support to synchronize the pvm_keep_and_clear

manager: Add some attributes to BIOS restore

This commit adds support to synchronize the pvm_keep_and_clear
and pvm_create_default_lpar BIOS attributes to the UTIL/D1
keyword in the motherboard VPD.

The use-case for doing this is the same as the other attributes we
already handle - that to restore them post a factory reset.

pvm_keep_and_clear - Backed up to UTIL/D1, bit 0
pvm_create_default_lpar - Backed up to UTIL/D1, bit 1

manager: Update BIOS Attributes only if needed

This commit adds a check before updating the FCO and AMM
BIOS attributes. If the attributes are already the value that
we are trying to update, we skip the BIOS attribute update.

This helps eliminate unnecessary BIOS updates being sent to PHYP.
