[RUM-6875] Use BigInteger from big-integer instead of bigint

[marco-saia-datadog]

What does this PR do?

Refactors all usages of bigint to use the BigInteger type from big-integer instead.

Motivation

Support for bigint is not stable across all versions of React Native and Hermes. It was officially introduced with RN 0.70.0 for Hermes, and our polyfills were not accurate. Instead of modifying the polyfills, this PR opts to directly use the big-integer library by default. This library will just act as a wrapper for the native implementation if possible.

Additional Notes

Other changes

• Adds the dependency in the 3rd party licenses
• Removes our polyfills (packages/core/src/polyfills.js)
