fix(app): RHIDP-2266 add condition error handling

[gashcrumb]

Description

This change adds exception handling to the two points where plugin supplied condition functions are evaluated, once when rendering the catalog entity tabs, and a second time when a plugin's mountpoint configuration is being checked. This change also makes the ApiHolder context object available as a 2nd argument; available at the second evaluation point.

How to test changes / Special notes to the reviewer

An easy way to test this is to throw an exception from here and use this plugin. The configuration for this would look like:

    backstage-plugin-simple-test-components:
      mountPoints:
        - mountPoint: entity.page.overview/cards
          importName: SimpleTestComponentsPage
          config:
            layout:
              gridColumn: "span 1"
              gridRow: "span 1"
            if:
              allOf:
                - isAvailableYes
            props:
              text: 'Content Block Two (always available)'

Verified this is working great. I have this config

          if:
            allOf:
            - isAvailableUsingContext

As well as an exception in simple-test-components/src/plugin.ts

export const isAvailableUsingContext = (
  _entity: Entity,
  _context: { apis: ApiHolder }
) => {
  throw new Error("Test exception for isAvailableUsingContext");
};

When tested on main branch it throws an error and breaks the entire UI. While with this PR's update it loads the rest of catalog entity tabs only the simple-test-component doesn't get load. Also the warning in console shows up as expected.
