Initialize the browser to display the specified configuration forms.
This function is the primary interface to the internal forms-based browser.
The forms browser will display forms associated with the specified Handles.
The browser will select all forms in packages which have the specified Type
and (for EFI_HII_PACKAGE_TYPE_GUID) the specified PackageGuid.
@param This A pointer to the EFI_FORM_BROWSER2_PROTOCOL instance
@param Handles A pointer to an array of Handles. This value should correspond
to the value of the HII form package that is required to be displayed.
@param HandleCount The number of Handles specified in Handle.
@param FormSetGuid This field points to the EFI_GUID which must match the Guid field or one of the
elements of the ClassId field in the EFI_IFR_FORM_SET op-code. If
FormsetGuid is NULL, then this function will display the the form set class
EFI_HII_PLATFORM_SETUP_FORMSET_GUID.
@param FormId This field specifies the identifier of the form within the form set to render as the first
displayable page. If this field has a value of 0x0000, then the Forms Browser will
render the first enabled form in the form set.
@param ScreenDimensions Points to recommended form dimensions, including any non-content area, in
characters.
@param ActionRequest Points to the action recommended by the form.
@retval EFI_SUCCESS The function completed successfully
@retval EFI_NOT_FOUND The variable was not found.
@retval EFI_INVALID_PARAMETER One of the parameters has an
invalid value.
