[PATCH] BaseTools:Build fail if define [DEPEX] in library inf

["Fan, ZhijuX" <zhijux.fan@intel.com>]

When define [DEPEX] in lib inf to build, it will fail and report"
gUefiOvmfPkgTokenSpaceGuid.test1 used in [Depex] section should be
used as FixedAtBuild type and VOID* datum type in the module."
But we define this PCD to FixedAtBuild type and VOID* datum type indeed.

DEC:
[PcdsFixedAtBuild]
gUefiOvmfPkgTokenSpaceGuid.test1 |
{GUID("4096267b-da0a-42eb-b5eb-fef31d207cb4")}|VOID*|0x3c

DSC:
add pcd under lib inf as below:

NULL|TestPkg/TestLib/TestLib.inf
 <PcdsFixedAtBuild>
    gUefiOvmfPkgTokenSpaceGuid.test1 | {GUID(gUefiOvmfPkgTokenSpaceGuid)}

Lib inf:(TestPkg/TestLib/TestLib.inf)
[Depex]
gUefiOvmfPkgTokenSpaceGuid.test1
[FixedPcd]
gUefiOvmfPkgTokenSpaceGuid.test1
