fix(juno): resolve BL2 RAM overflow with RSA+ECDSA in GCC(14.2.1)

* Using "TF_MBEDTLS_RSA_AND_ECDSA" algorithm with toolchain 14.2.1
  causes the BL2 image to exceed RAM limits, triggering a link error
  ("region `RAM' overflowed by 4096 bytes").

* Resolved by increasing PLAT_ARM_MAX_BL2_SIZE by 4KB to accommodate
  the larger image.
