Remove all "depends on !PV_SHIM_EXCLUSIVE" (also the functionally
equivalent "if !...") in Kconfig file, since negative dependancy will badly
affect allyesconfig. Although "if !PV_SHIM_EXCLUSIVE" for CONFIG_VGA is not
truly a dependency, setting PV_SHIM_EXCLUSIVE y still makes it unconfigurable.
So we remove it here too

Add "#CONFIG_xxx is not set" for above options in presets for x86 PV shim, as
the explicit declaration is to ephasize setting for the shim is different
from the general default.

last commit.

v2 -> v3:
- remove comment for PV_SHIM_EXCLUSIVE
---
v3 -> v4:
- explicitly state "CONFIG_xxx is not set" in "pvshim_defconfig"
- Add "default y" for SHADOW_PAGING and TBOOT
- refactor commit message
---
v4 -> v5:
- For not breaking allyesconfig, changes to defaults are actually not needed.
So remove them all
- Leave one blank lines
---
v5 -> v6
- add description for change: removing "if !PV_SHIM_EXCLUSIVE" for CONFIG_VGA
